First of all, I apologize for bothering you guys, haha.
So the bug - as the title says doesn't allow me to eat, place, or craft anything - let alone use the oven (and yes, my spawn protection is 0). I can normally craft wooden planks and such in my inventory. I can kill peaceful entities and aggressive entities, though. I play with 35 mods that all go well along! In Singleplayer I can use the oven, eat and such, so I'm extremely confused as to why I can not do anything in multiplayer (neither I nor my friend). I gave myself and my friend op - it still didn't work, and even made a separate account and server (which didn't fix anything). I sincerely beg of you guys, please help this poor soul out here, ah. I'm gonna link my mods and log, here you go guys:
