I am in the process of constructing a squid farm and have encountered some frustratingly low spawn rates thus far.I have set up a 20 block x 20 block, water filled area which is 16 blocks high. It was built between levels 46 and 62 which is the standard Minecraft squid spawning range. The squids fall through a barrier of signs at the bottom and drop 26 blocks to their death where their ink sacs are collected by a series of hoppers.The farm is located in a desert biome and is over 80 blocks away from the nearest natural water source. The surrounding surface area has been slabbed out 64 blocks in any direction to prevent mob spawning and I have also meticulously illuminated surrounding caverns with torches.Empire Minecraft mob spawning limits state that "Mobs are limited to spawning in clusters of 2. A cluster size is 20 blocks X/Z, and 16 Y. If there are 2 monsters within the cluster of where an entity is trying to spawn, the spawn will be cancelled. Natural spawning will continue until every player has 90 monsters in their range." Do these rules also apply for non-hostile entity spawning? I have satisfied all of these conditions and yet sometimes I go for painfully long periods of time with no squids spawning at all even while standing at an AFK location 30 blocks away.Am I missing something? If so, is there anyone out there more technically savvy than myself who can illuminate for me what I am doing wrong? Thanks!
