That was my bad guys, I just accidentally changed the spawn location during testing. If it happens again just yell at me and I'll fix it as fast as possible. Your saves are still there so don't worry.
Also I adjusted the xp formula for the enemy leveling system so you should be gaining xp again. If it continues having issues I will disable it until I figure it out more.
Reminder: Never finalize an update while sleep deprived
