Bug - Fixed Thunder thigh qty is not tracked correctly

Something is wrong with the way the quantity of thunder thighs is reported. This may be related to what happens when you use one when you already have all the thunder skills.

I just got a thunder thigh drop.
I used it, got You can't learn anything else from this, so you just throw it away.
print(item_amount($item[thunder thigh])); >> 1.

The problem resolved itself when I restarted Mafia (it now correctly reports 0 thighs). Is this a game-level bug, given that an inventory refresh seems to do the trick?

Revision 14697 removes the item (and similarly for the aquaconda brain and lightning milk) if you "just throw it away" rather than going to the choice adventure that lets you pick a skill. Untested.
