I think I see the problem.
Level time: 0 game time, 0 day time
Level dimension: 0
Level storage version: 0x00000 - Unknown?
Level weather: Rain time: 0 (now: false), thunder time: 0 (now: false)
Level game mode: ~ERROR~ NullPointerException: null
The game mode was originally survival. When I opened to LAN so my brother can join I changed game mode.
I logged out being in creative mid-air. Maybe it crashes because I am supposed to be in survival mode?
So is there a way to change my game mode without having to be in-game?
Okay, so what does this mean? Assuming I know nothing about this.
There are no spawners, none that I know of. I do have a Villager "breeding center" in that area though.
Closing and reopening is not working either. Unless I'm doing it wrong.
-This issue was not happening before so I have no idea what could possibly be the problem.
Here is the crash report.
Sorry, this has been resolved. It was just a problem with the world save, probably got corrupted.
