Fix logic problems

Bit of a vague title and description, but there's been people that have had Talon Trot be shuffled behind the ramp inside Gruntys Lair for example, and some problems with jiggy jinjos not actually having enough jinjos to be received before the reward is needed.

I have no clue where or how deep the problem lies for these, so just putting a blanket issue in for this for now.

Start by reproducing the Talon Trot placement problem in Grunty's Lair and the jiggy jinjo reward scenario, then trace the game logic that handles their placement and required jinjo counts. Done means Talon Trot is not shuffled behind the ramp and rewards are available only when enough jinjos can actually be received.
