After playing the server for a little while i have created various grinders that are proven to work and are very effective and efficient, however they seem to have no output on this server. I have created a creeper farm and a drown farm and seen ZERO spawns after 12+ hours of afking at the locations. People have suggested i make them larger, but this seems useless considering anything x 0 is still 0. I have noticed various people have had the same problem and i have had various different donators/moderators come take a look at my creeper farm and not a single one can identify an issue with it and explain why there have been no spawns. I understand that spawn rates are shared amongst the server so spawns will be slow, however I expect a couple per hour atleast. We have even gone to the trouble of lighting all the caves in the area to prevent any other mobs from spawning. If mobs are unable to spawn at all then what am i supposed to do, never make a grinder? Would appreciate if anyone has any insight into this.
