I can confirm the self-aware "animal" spiderbot, but am unsure how Trorbes determined that the robot had mecha skills (I suspect Trorbes had the bot "learn a new skill", and got the message "Spiderbot learned Mecha Piloting!" or something).
The bug is triggered by having a roboticist with science skill 5 create an arachnoid robot with enough part points (armor, base, power, and computer) to trigger a self-aware robot in previous versions. One of my self-aware "animal" spiderbot was created with industrial powerpacks, gunshields, three goggle-computers, and various weapons and armor.
Speaking of bugs, I won over a lancemate at the Cavalier's Club, then took my new buddy to see my old friend at Third Square Plaza or whatever. But, old friend wanted me to join him in fighting pirates. I agreed to to help him, and suddenly my previous lancemate is kicked out of the team. I leave, and am told that I can't go back in the Third Square Plaza. Now, when trying to call my first lancemate, the game tells me that "[character] isn't in the local calling area".
