Some chunks became completly dark, in there they spawn mobs and they dont go away after placing down a torch, they stay this way. The porblem started when i converted the world to 1.14 pre1 at 1.14 pre2, when i converted to 1.14 pre3 it seems that was fixed but then i died and the chunks reloaded and have still this bug. Pls fix i have only creepres around my house.
