I and my friend are playing on a private server. at first, everything was OK, but one day, i noticed that monsters have stopped spawning. nether was still... well, hell and the twilight forest hollow hills were still filled with goblins and redcaps. We deleted the level.dat and renamed level.dat_old to level.dat . It helped, but soon, the monsters spawned less and less until we ended in a similar situation we were before. i tried to make render distance larger and then deleted level.dat and renamed level.dat_old to level.dat, but that didnt help eighter. i remember on my old server that we were getting swarmed with monsters, but now, i have problems even finding a skeleton! Anyone knoes how to fix this?
