My servo is now a cyborg. I had him change into "everyday" but that did nothing; then I had him change into "formal" and he changed into a tattered jacket with tails but is face is now half-human half-servo. I tried this with another servo (who is a female) but it didn't work. I'm thinking maybe it's because I had him workout, so he became fit, then when I had him put on his clothes, they didn't fit anymore and he "busted" out of his servo cover-up. Who knows. Has nothing to do with that.
I've tested this.
When activated by a female, a female servo will have the "face" when in formal outfit.
When activated by a male, a male servo will have the "face" when in formal outfit.
When activated by a female, a male servo will not have the "face" when in formal outfit.
When activated by a male, a female servo will not nave the "face" when in formal outfit.
Another stupid Maxian bug.
I also had this bug. I just used my last two guidelines to fix it.
Simple Solution:
Activate by the last two guidelines.
