Last choosen plant bug

When you place a “specific-use” plant in the last slot of your loadout (for example, choosing Cactus to counter Balloon Zombies), the game behaves as if you didn’t select it. It ignores that plant and still shows the warning that you haven’t picked a counter for that zombie type.

My guess is the game might be validating selected plants by iterating from index 0 to < n, while the last plant’s actual index is n, causing it to be skipped.
