I can confirm this. Playing 10110, Android 64-bit on a pixel 3xl. Happens when using the "/" menu and I press ",".

It's not just the dropping of large amount of items that triggers the issue, it's dropping several stacks that have multiple items. In this save you can reproduce the bug by dropping the entire inventory.

It looks like the game is not actually frozen, per se, because dropping 5 stacks causes a massive slowdown but eventually resolves.

And in this save, dropping the entire inventory happens without an issue, because every stack only has one item.

Can confirm, dropping eg. 50 cash cards and 5 glass bottles caps out one core and allocates all available memory.

Yeah, that fix made the game kaput.

I tried to drop items on the latest experimental build and i use windows 10, but it only dropped one at a time for me. it was not a huge stack of items, but for some reason dropping my stack of 3 rags on the floor resulted in only one being dropped at a time

You have to try to drop multiple stacks of items.

tried kelenius's save, dropped everything in my inventory including my clothing. this was the third test, after dropping 300 plastic chunks and 100 mutant meat in addition to all of my clothing

Well that's odd, but it's happening on all three computers I've tried. I wonder what is different for you?

confirmed on my machine - Linux - lubuntu with Kelenius save.

In the issue for the "can only drop 2 at a time", they hypothesized that it was #36205 that caused the issue. At this point, even if the new method is theoretically better from an optimization standpoint, might it not be better to just revert that one back until we identify the issue it's causing and manage to find a good fix for it?

Ah. Good to know, I don't need to save scum/force quit then. Getting the same. More items dropped more chance, but does happen when just a few items dropped. Specifically for me dropped in a vehicle, but not dropped much on the floor to know if that is a candidate too.

I have this issue as well when dropping a stack of 32 threads onto ground. If I drop then one by one, they can be moved without a crash, only the 'M'ove all command will crash it.

Have tried numerous scenario's (eg: dropping on bench, ground, travois, different squares etc) all with same result.

Interesting to note that it only crashes when moving items FROM inventory.

I had this problem while playing yesterday but not today. The difference is that yesterday i had autoloot (loot all) turned on because i was foraging the forest. Today i remembered to turn it off.
