Okay I was in mob arena, around wave 38 the chat went white, like a server restart, but it didn't restart. I wasn't the only one who got this. Everyone did, after that is went to normal, around wave 40, I saw the mobs were giving exp, I was like wtf. I died at wave 41 or around, but I died like I would outside mob arena (with respawn option or go back to main menu) I click respawn, instead of going to the mob arena spectator room, I go to my island, no rewards from mob arena or nothing!

 

No clue how that could affect this... and like I said almost everyone's chat went white like a restart.
