ToME: the Tales of Maj'Eyal

When I first unlock transmogrification chest option (in a newly-installed game), there is a pop-up message saying that I've discovered an old fortress and that a strange creature has given me the chest. However, I've recovered the chest from a dead Troll. I guess the pop-up message should be changed...

Thank you. But how do I do it?
