I hear the mobs everywhere! hear them, get attacked by them (a skelly shot me), and they still get in the way when placing a block. I can even use /butcher to get rid of them... but I cannot see them/attack them. All plugins I have disabled (so it is not plugin issue) I have no idea how to fix this. Someone else had this same issue, their issue was memory which fixed it. I thought this was true. I was able to increase RAM from 1GBto 12GB and the issue persists. So I'm not sure what else to do, as I have tried everything else.
