I'd update this for the next update. When it 1.3 or whatever the next one is, suggest not around 1.2 since a new update would come soon after, IF you are updating this again.
I remember using this mod in 1.7.3 and LOVED IT. Mixed together with aether mod and some others made this even more fun. Aah memories
Looks very interesting! Good luck getting this updated, and I hope you eventually implement a way to get the companions to stay in a place upon command. Perhaps some sort of staff of power created with the souls?
