ToME: the Tales of Maj'Eyal

Upon reaching my fortress as a skeleton reaver, I activated the orb, library, spoke with the butler, hit every topic. After the LAST topic finished, he raised the topic about syncing my cloak so I wouldn't have to wear it. I did not (for obvious reasons) have the energy for it, but since I was speeding through all the dialogue by rapid-tapping enter, I ended up hitting 'yes please, do that for me' (or whatever it is.) Dialogue closed. I later came back with the 10 energy necessary, and he would not raise the topic again. After removing the cloak, I discover that I still have the effect, eve though he did NOT consume any energy at any point to do this.

So basically, I got the cloak upgrade for free, or my cloak bugged. Probably the former.
