Fixed Maple Tree Party Quest Bugs

During <Stage 4> (snail map), if your inventory is full, you cannot pick up extra items (i.e. snail shells) even if you try to clear some space inside the stage. If you were to re-organize your inventory, nothing happens; and if you try to sort it using the Slot Merger button, your client will crash after the second click (when it tries to Item Sort) with no error message.
Additionally, when you exit the map, all items that are dropped (including the snail shells) would be returned to your inventory. There's also a similar mechanic to that of GPQ's Stage 3 where the items are bound to whoever killed the mobs (i.e. another party member can't loot your snail shells, or any other items that you drop even if it's a perfect weapon or a chair in that specific map). I assume this has something to do with the bug where the game still detect your dropped items inside your inventory as "ghost items."

A workaround for this is to exit the Stage, clean your inventory outside, then re-enter to complete the stage.



Additionally, on <Stage 2> (mage map), there's a chance of candles not being spawned twice after killing the two cakes (i.e. only 5 candles spawned instead of 10) -- there's only one blue notice of "the candles have been spawned!" instead of two. I couldn't replicate it yet so there's no recording, but so far two occurrences happened pretty randomly:
-1st run was when the cakes were both killed at the same time using a mage after clearing all the initial candles first;
-2nd run was when the cakes were killed in succession while the other candles are not all killed, but the second cake died around the same time as the blue notice of candles spawning appeared.
