Is this singleplayer or are you on a server?

I tested it with both single player and multiplayer and got the same result. Once I get back home I can test it without any other mods to see if it is caused by a conflict

didn't mean to close the issue, my bad

It seems to only happen when using the Moreculling mod

this is a bit concerning just because I believe both CITR and Moreculling are included in the popular Fabulously Optimized modpack

I did some research and I see this is a known issue, so ill close this
