PS: Why is the diamond dolly even enabled in the pack? It's basically a cheap, reusable portaspawner....
I think it's on his "to do" list. I agree, it solves way, way too many problems and makes mob farms extremely easy to make. However, I've found some very interesting complications with spawners from dungeons. Has me wondering if it's a change to spawners in the whole pack, or just the ones in the dungeons.
