Hi, I'm using a custom terrain world and I've found an alarming problem; with no plugins mobs only spawn in a handful of chunks on the entire map. I've installed plugins, //butcher'd and /gc'd and found that basically all the mobs are within these chunks. They don't spawn anywhere else... I've tried this with default spigot, bukkit & paper spigot configs. Is there a plugin that can be made to go around this? Why is this happening? The developers I've msg'd have absolutely no idea why this is happening :s. Thanks, Ferx.
