Screenshots

[snips86x]

The screenshots you have provided relate to a patch that was dropped today for Valheim. You will need to opt-in to the 'previous stable' release via the Beta menu within the steams game properties and use the following to update the server to use the previous stable:
app_update <app_id> [-beta <betaname>] [validate]

[kblaschke]

@snips86x This might be a workaround for now, but not a viable one for those who want to use crossplay or have no control over server updates.

It looks like Valheim devs changed the Chat class a bit and now HarmonyX can't patch the code anymore and fails, which then leads to all kinds of issues as the game will run on half-patched code. There might be other functions that were changed though.

[lyoumi]

Yup. At the moment I changed game version to the previous stable one, nut agreed that this is temporary workaraond. Do you planing some fix for upcoming Valheim version?

[mdbdb]

I run a Valheim server in the local network. I use https://github.com/lloesche/valheim-server-docker for this - V+ is already integrated there. Since I am not able to use the previous version in the Docker container, I have now copied the saves from the server and activated V+ locally on my computer with the above workaround. It works for now.

However, I hope that the developers will keep working on V+ and fix the bug.

How do you change the game version to the previous one? Tried searching for a solution, but can't find one.

Someone on reddit suggested this, but I haven't tried it myself:

Steam > Valheim > Properties > Beta > default_old

Could someone let me know where to run this command app_update <app_id> [-beta <betaname>] [validate]

I use Gportal as a host and I'm not sure where to get in to run it. Is this even an option if I'm hosting with Gportal? TIA

[PedrinElPhreak]

I run a Valheim server in the local network. I use https://github.com/lloesche/valheim-server-docker for this - V+ is already integrated there. Since I am not able to use the previous version in the Docker container, I have now copied the saves from the server and activated V+ locally on my computer with the above workaround. It works for now.

However, I hope that the developers will keep working on V+ and fix the bug.

So I managed to apply the workaround in my server created by the same docker.
Here's How.

You will need to keep the docker running

Then from the server terminal, you'll access container terminal using:
docker exec -it vhserver-aline /bin/bash

then you'll need to put the -beta flag inside the 'valheim-updater' script by running
vi /usr/local/bin/valheim-updater

Then will open VI text editor
This file will have a line like this

download_valheim() {

so two lines below, will be the command that updates valheim
You'll need to put "-beta default_old" after the app-id.
IMPORTANT - To edit with VI you'll have to press 'i' to enter in insert mode, and will have to digit the text, since paste didn't work for me.

-beta default_old

After editing, press esc to leave the insert mode, and then press ':wq' for Write and Quit

Here is how my line gets after the change.

/opt/steamcmd/steamcmd.sh +force_install_dir "$valheim_download_path" +login anonymous +app_update 896660 -beta default_old $STEAMCMD_ARGS +quit

Works well for me. Hope this can help you.

It works for now.

If you use that docker container, it doesn't need to be so complicated. Just add the STEAMCMD_ARGS environment variable and restart the docker container:

version: "3"

services:
    valheim:
      image: lloesche/valheim-server:latest
      ports:
          - "2456-2457:2456-2457/udp"
          - "8080:3000/tcp"
      environment:
          - "SERVER_NAME=A server"
          - "SERVER_PASS=${PASSWORD}"
          - "BEPINEX=false"
          - "VALHEIM_PLUS=true"
          - "STEAMCMD_ARGS=-beta default_old"
      volumes:
          - "./.files-valheim/config:/config"
          - "./.files-valheim/data:/opt/valheim"

For each client, change Steam Beta Option (steps provided by the Discord channel):

1. Open steam library
2. Right click valheim
3. Manage
4. Betas
5. On the first field, click it to get the drop-down menu and change to default_old

Tested and works

[mdbdb]

Tested and works

Yes, thank you. That works for me too. However, I hope that V+ will be updated in the very near future.

[losciamano]

For folks using mbround18/valheim instead of lloesche/valheim-server the env var to pass additional parameters to is ADDITIONAL_STEAMCMD_ARGS (this is documented on their github but not on docker hub).

Tested this today and works for now.

[smietanka]

Someone trying to fix that?

[healiha]

This will be fixed by #710
We're waiting for @nxPublic to be back as he's the only one who can approve the PR and create the release on github.

In the meantime, you can use the pre-release .dll which is available in the #alpha-releases channel of our discord.

[jdrusso]

As of last night, @MartenBE 's -beta default_old fix for the https://github.com/lloesche/valheim-server-docker container no longer works for me :(

[SSimp258]

The reason it no longer works is the "default_old" version is now 211.7. The only workaround now is to get on the Valheim Plus Discord channel and get the alpha version. NX will be back this weekend to publish it. Once it gets published, Thunderstore and Nexus will work as normal.

[jdrusso]

The following has temporarily resolved this for me with the https://github.com/lloesche/valheim-server-docker server container, using the alpha release DLL:

1. Attach to container (docker exec -it valheim /bin/bash)
2. Replace the DLL in /opt/valheim/plus/BepInEx/plugins with the alpha release, from discord
3. Kill the currently running server with kill $(cat /var/run/valheim/valheim-server.pid)

The container will automatically run a new server process to restore the one you killed, which will load the new V+ DLL, and the logic to download V+ from github appears not to be run

I left -beta default_old on both the server + my client, but I'm not sure if it's necessary, I'm just lazy and it worked.

[avaryx]

To follow up on what @jdrusso has provided, I did the following:

1. I downloaded the alpha ValheimPlus.dll from Discord
2. I backed up my current ValeheimPlus.dll in my server directory, and replaced it with the alpha version
3. I started up the container and the logs were fine

Note that the DLL is found here:
./valheim-server/data/plus/BepInEx/plugins/ValheimPlus.dll

I did not do anything with the -beta default_old settings but rather kept my server settings the same as they were before.

[healiha]

Closing with 0.9.9.9 release.
