Having a real issue with mobs not spawning. I have played numerous skyblock/factory servers so know the right height, shapes, distances etc but on this server despite several rebuilds at various other heights and distances I am not getting many mobs. IN fact I do actually get a mob occasionally and on some instances as I walk over to attack it it despawns.

Is this the server? MY other account playing the same server I get hostile mobs and have 5 liquid cows but no other passive mobs spawn. The distances are exactly the same, as is the design.
