okay yeah that's kinda expected then. the game won't let you go to another dungeon afterwards while you have any jobs; this behavior can be seen in base Sky with multi-segment dungeons like Steam Cave or Amp Plains. I do have plans to rework the Zero Hoard idea for the next update, but for now uh...if you wanna access the Hoard, don't take any jobs for that dungeon.
it's possible...hell, I could implement it within like 5 minutes. However, if I did, either it would be available to girls only, or the guys would be stuck with a starter that can't evolve. So I can't really see myself doing so unless, like, Tyrogue gets starter animations so I can keep the genders balanced.
However, I *am* making the quiz easier to edit in the next update, so if you're willing to crack open SkyTemple yourself it should be pretty simple to do since Salandit is already available in this hack!
