ToME: the Tales of Maj'Eyal

Hey all, great game you've got here, I've been having lots of fun. Unfortunately I accidentally screwed up 2 quests by messing around with the save files (accidentally deleting the .teazs). Specifically the "The Beast Within" and "And Now for a Grave" quests. Basically the problem is that I have the quests in my journal, but the dungeon entrances no longer show up on the world map for them so I can't enter them. I understand that both of these quests give out classes for later use. This is on my first character that I've manged to not lose instantly with so I would like to be able to complete these quests. I messed around in the Lua editor for a little but I can't really make head or tails out of most if it so I was hoping someone could tell me how to remove the quests from my journal or otherwise restart them. Hopefully then I can just go back and get them from the normal spots.
