It seems like Feathers is trying to send network packets when it shouldn't be able to, resulting in a crash, this happens when reloading resources, particularly tested via switching resource packs.

Same issue here

Looking at issue reports for Elenai Dodge, the general consensus seems to be that installing PlayerAnimator would fix this. It did not in this case.

Thanks for spotting this! I'll get working on a fix 👍
As a side note, feathers does not use Player Animator, that was an issue with Elenai Dodge 2 that is now (hopefully!) resolved).

Thanks for the crash log too :)

Unsure if you have figured it out already, but it only happens on the main menu! Changing resource packs inside a world has no problems.

still happening on 1.18.2 😕

Sorry for taking so long to get to this! I'm looking into this at the moment, but so far I'm unable to reproduce the bug, out of interest for anyone who can help, does it crash for you both when inside a world and on the main menu?

Thank you!
