This version has incorrect permission nodes. Instead of spawnercollectors.command.<command>, this one uses spawnercollectors.<command>. This will be fixed soon in the next update
Important: If you are using legacy minecraft versions, you will have to change material IDs to legacy IDs. For e.g. different wool types, use e.g. WOOL:2
