Ever since your patch to fix the xp glitch with a furnace (update) mobs spawn when owner is in the world (even with two players) but when you have three in the same world hostile mobs stop spawning and the hostile mobs that had spawned and when an extra player joins hostile mobs vanish instantly. We never play peaceful mode and "NO" cheats are enabled but hostile mobs keep vanishing when extra players join the world and when one leaves on a night cycle hostile mobs appear instantly. Please fix this issue its ruining my gaming experience!
