I def had a T1 android spawn with immortality. Only thing I'm noticing is that he is isn't regrowing limbs. He regrew his vocal chords (Can't remember what the part is named for androids) But not the shoulder.

He is a greater Immortal at this point, I've made sure and even bumped the healing factor for greaters up to 21 since the shoulder is a 20hp part. He won't regrow.

I also have Rim of Magic installed, so far no natural crossovers, but also no apparent issues.

Good luck friend!
