Whenever I try to give XP as a reward no matter what the amount the player goes down to lvl 1 and has -15982349(some number like that) XP.
I can level them up manually but something is very broken here. Also when a player kills monsters it doesn't reward them XP.
Also: Does anyone have a table for Xp to level? If i can't rely on the game to auto reward for killing monstres i have to know much to give my players.
I ran into this problem as well, it can't be removed so you have to restart your campaign. One way around this that I use is to spawn mobs and enter them into combat. then kill them with the DM tool. Hope this helps, best of luck!
