I think this is working as designed. You can certainly tell a mute what to do but they can't exactly talk back. Eventually you can remove negative traits, which will unlock their ability to tell you what they need. I'm curious though if trying common level uncap methods like upping their grade, giving them a specialization or having them win a fight can unlock the next level even if you haven't "discovered" it.
I'm actually seeing something similar to this when applying armor in 0.5.3.1d I believe the problem lies in that the slave variable in items.gd does not get initialized for the the functions armor, agi, stren, maf, end or beauty. Adding "slave = globals.slaves[get_tree().get_current_scene().currentslave]" to each of these functions seems to fix this.

Noticed in exploration.gd on line 1220 you have: slave.dom = rand_range(6,12)
I think it's meant to probably be: slave.dom += rand_range(6,12)
slave.dom starts between 40 and 60 for most slaves and given the context, I think it makes sense that you're trying to increment their dom value, not reset it to between 6 and 12.
