[bug, csc] Reverse gearing adds temp stats to other stat permanently

i started out with a 40/55, Potent Injected it to make it a 20/55 with 65 temp attack (85/55), then reverse geared it, at which point it became a 120/85. at the end of the turn, it dropped to a 55/85. as far as i can tell, the temp attack stayed on after the reverse gearing, being added to the new attack but was also used to determine the new permanent life.

Tried it again with Glomp. My 67/67 with +100 temp life became a 167/67 with +100 temp life.
