There is a bug, sometimes when you turn off the resource pack in the settings, it remains enabled in the game. Updating F3+T textures doesn't help. By removing the mod, the problem disappears. I used this mod to download custom totem textures for the server. In the screenshots, I turned off the xray-pack, but it remained on in the game. Perhaps this is due to the fact that the resource pack with totems is loaded when logging on to the server and it somehow breaks the mod, but it's impossible to say for sure.
