Re: I'm not sure what treasure you're referring to sorry. What gave you a hint that Lord Balcon had a big treasure?
I haven't played this mission in many years and have forgotten a lot of the finer details haha
Re: the bugs you found, those are quite interesting! When the mission was released there was an issue with that safe I believe, but the shadow bugs weren't there. That does appear to be a problem with running an old mission (I think this was a 2.03 mission) on 2.10.
However I do plan to go through and update all of my older missions for 2.10 at some point, so i'll add those bugs to my todo list, thank you!
