is it normal that a lot of trade-in-for-stats/caps quests that you can turn in multiple times disappear before you reach the limit?
I noticed it with the stones for stats and magic fibre for seed cap quests.
to everyone having problems with Dim Cave: the weakest to strongest attackers sorting works well while your pets are max level and fully seeded - i did the thing with Lesser Devil Familiar at 8 - you may have to try a few times as some enemy combinations are easier than others
having the game crash right when you get to the victory screen of a challenge removes the key you used but does not award anything (it resets progress to before you accepted the challenge)
