When I go into the E menu and go into the skins menu the game will crash. I tried with no other mods and got the same result.

The game crashed whilst rendering screen
Error: java.lang.NoSuchMethodError: 'void me.suff.mc.regen.client.screen.IncarnationScreen.renderToolTip(com.mojang.blaze3d.vertex.PoseStack, java.util.List, int, int, net.minecraft.client.gui.Font)'
Exit Code: -1

Nice CPU, will look into this tomorrow then

Thanks

No I don't have it installed

Did you happen to have TARDIS mod installed aswell?

Forge build version and Mod version please

Forge 37.0.85
[1.17.1] Regeneration - 1.0.1

Thanks, will investigate this soon

Would you happen to have a more complete log?

Kay, so it turns out this is a bug within Forge and they will have to fix it
I'll let you know when it is fixed, for now I will mark this issue as forge bug

Ok, thanks

Sorry for the trouble, fix is on the way: MinecraftForge/MinecraftForge#8154

Update to 1.17.1 - 37.0.88 :)
