I was fooling with time and set it to a negative value using the in game command "time set -100". The world immediately crashed and will no longer load. It crashes to desktop with the initial error:
m[1;31m[20:23:06] [Server thread/ERROR] [ne.mi.ev.EventBus/EVENTBUS]: Exception caught during firing event: Time cannot be negative!
Obviously now looking for a way to manually edit a world file to reset the time. Alternatively is there a file I can regenerate that controls time while doing the least amount of damage to the save?
