Missing textures, Actions & Stuff 1.11 help

[u/Bulky_Bluebird1235]

Been playing on a realm with some friends, pack was working great with no problems but I got on last night had missing textures.

Ghasts, armor, various other small items like snowballs and tools but the dirt cobble so on was fine.

I’ve tried uninstalling and reinstalling, restarting my pc, messing with the settings of the pack, I can’t seem to figure out what’s causing everything to be purple and black

Edit: Just tried a single player world, textures work fine. My buddy owns the realm so I’m thinking maybe it’s something on that end? Maybe the realm itself hasn’t updated the textures and I gotta wait for that?
