Yes bounty hunting worked great - you should increase XP gain a bit - I dont know how much you get via tracking but that 1 XPsh per crab is way to low ^^
I didnt find the ol' crab ^^ But the thing is because of missing minimap for that area its hard oriantating
What Option do you use to check if the Player has Gold in inventory? I think your issue might be due to frame delays if you query the result of the check to early before the check delivers result you will get no correct response. (Larian Update wiki about Frame delay - this caused so much Frustration on my site the last days...
