Actually, it's a feature. Mousy got greedy and sent Piggy to the void so they could take all the money for themselves. My only criticism is that Mousy didn't wait till Piggy got more loot before doing so ;)
Sad there's that bug. I didn't get a chance to fix this 100% before submission. I got rid of this happening on my play tests, but clearly it's still there. Hopefully it doesn't happen too often.
Thanks for playing~
