Its common bug happened to me recently too. Go at General Support forum and make a detailed post there (number of spawners etc) And also open a ticket at discord as its mentioned at Kieran's thread: https://differentcraft.net/forums/threads/faster-support.3506/
@Crane_L Has this been sorted for you? The staff don't check the forums much anymore. It's recommended you make a ticket within the discord server for a faster response
