Okay, so when I go into the spectre dimension on my server it is just black. Sometimes it does appear after a minute and I can move around but 99% of the time it just stays black till I leave the spectre. It can't be the modpack because I have went into single player and it worked fine. I've also tried deleting the whole dim file/folder, which did not work. Any ideas?

NOTE: It does however load when I am in creative mode or switch into it while in the spectre dim.

Can you reproduce this without any other mods installed?

I am on a server and it only happens when I'm on the server. I tested it with just random things and it worked. I also tested it with all my mods in single player and it worked. It appears to be a server incompatibility. On the other hand, my friend and I have found if you wait for about 15 seconds it will load. But you would probably agree that that's a pretty long wait on top of the dimension loading. Any ways of fixing this?(Sorry I can't reproduce this without mods installed because I'd have to delete/move all my server mods and saves so it's just to risky)

quick edit: seems to be a rendering issue with the dimension. It does not display my character nor does it show me changing my hat from the hats mod.
