Would you consider adding possibly biblio craft and necromancy? biblio craft would add armor stands,and of course necromancy you can create your own monsters.
I don't control which mods go in but thanks for the suggestions. We might see bibliocraft reappear because we had it before. (I know from my own experience it has a weird crash if you use a certain version with some mods which might of been why it got removed) As for necromancy it can be a fun mod but unfortunately it doesn't have a lot of content. I know a lot of people in Attack of the B team where the mod was in didn't use it an awful lot so I'm afraid its not likely to be added. Thanks for suggestion though and I hope to be able to see armor stands and bookshelfs reintroduced as well!
