So, there's some bugs with my minecraft. But, only on multiplayer. There are no crashes. It's a very strange texture bug. A similar bug
happened on another modpack on a server hosted by the same friend that is hosting the one that this bug is on. The first time this happened was
on a modpack (I've long since forgotten the name, I was never able to get it fixed and I don't think anyone had a similar problem,
unfortunately), all blocks turned some shade of brown. But, only on multiplayer did this happen. In single player, it worked fine, no texture bugs, no crashes, etc.
Now, I'm getting a glitch where the pink and black invalid item texture is plastered all over my screen. See reference image.
The modpack I'm using is a custom modpack. I will list all mods that are being used below. It's easier if I just screenshot my mods folder, so then you also get the versions of each, as well.
The other glitch happened on a modpack with Lycanites Mobs installed. I suspect it may be the culprit. But I cannot confirm as deleting the mod would make me unable to connect to the server. The reason the others will not delete the mod temporarily is because no one else has this glitch, or has ever had this glitch.
I honestly have no idea what could be causing this. I've updated my graphic card's drivers. I've updated my java version. I've tried reinstalling the pack. Nothing is fixing it. And again, this is only in multiplayer.
Well... After much trial and error, I found out I was stuck inside of a block the entire time.
