Hi all, it's been a long time since I've done a playthrough of the Xania mod and noticed the link to the Goblin Vault in Lumi's laboratory so I had to find out what was inside. After clicking "explore" forever after getting the 500+ gold and becoming a goblin, I discovered Lumi laboratory in Dungeons. Oh well, this gave me time to go up a number of levels. So I bought the mech and found out immediately that I couldn't fight with it equipped. However, I don't see a way to unequip it or modify it so that I can fight.
Is this a bug, unwritten story, or am I missing something? I also bought a blueprint, but don't know what to do with it. Interesting additions to the story if I can just figure out what to do next.
