I'm hosting a little server for my friends and I. The mob spawns are fine for the first minute or so, and then they just drop terribly. Mobs start despawning and no new ones spawn, so we're stuck with maybe a creeper here and a crab there, but you have to wait forever for anything you want to spawn. Is there a way to increase the mob cap or spawn rate? Also, I wasn't entirely sure what section to post this in, so there's that.
