skin caches that are outside the Minecraft instance's folder make the game keep loading old skins, MultiMC stores it on MultiMC/assets/skins and TLauncher keeps it on .tlauncher/cache/ for example

😭 seems we will have to wait btw, MAKE A PR NEXT TIME WHEN YOU HAVE THE FIX DONE SO I CAN BUILD IT AAAAAAAAAAAAAAAAA (and everyone else knows its being fixed instead of empty silence)

No, the sad part is @xfl03 knew this and has done nothing since 1.16.x

Similar Issue to #174

yeah your case seems to be with Twitch/CurseForge launcher, i havent tried but have you checked if changing in CustomSkinLoader.json the "enableCacheAutoClean" setting to true makes it work

I don't think these two issues describe the same problem. This issue is caused by premature initialization of certain classes which prevents the assets/skins directory from being cleaned up. This has been fixed in my local, and I will submit the fix after waiting for 1.19.1 to be released.

Your issue and this one are apparently different, I'm sad that there was no info on the issue already being fixed. Imagine if I start fixing this when I later discover that someone already fixed it.
I do hope your issue gets fixed. :/
