I joined a multiplayer server yesterday and as I joined, the world was covered in magenta beds. I thought that this was part of the server until I discovered that the issue was on my end only. I found out that Blockus was the mod that was causing this issue. It isnt just a rendering issue either, as I use the mod Jade and that shows that the blocks are in fact what they are shown to be. I tried updating the version of the mod however that had no effect either. I am playing on Fabric 1.21.1, version 0.16.5.
