Warnings when dog teleports through (nether) portal

[FPSUsername]

Information

Server version: PurPur v1.17.1 build 2165
MyDog version: v0.1.1-alpha
Java version: AdoptOpenJDK 16 OpenJ9

Issue

When the owned dog enters a nether portal and the player doesn't, the server console generates a warning and an illegal argument exception.
I'm not sure if it's intended that the dog stays in the nether, but it returned back into the overworld once I slept in a bed.
This log continued every 10 seconds till the tog returned.

Hi there!

Thanks for the bug report!
I haven't been that active on the project lately, due to work and school, but whenever I get back to the project I will be sure to give it a look!
If it's breaking too much stuff and making the plugin unusable, I'll take a look at it as soon as I get some time to do so.

Cheers,
Hero
