UIM cannon decay is splitting it between inventory and collection box

[UlM]

If a UIM lets the cannon decay it will try to put all 4 parts into the inventory, if you have less than 4 spaces it will fill what it can and then put the rest in the box.
This leaves the player with parts they cant use, and cant store anywhere unless they empty the box again.

After doing so you'll need to let it decay again and make sure the inventory is full so all 4 parts go to the box for actual storage.

Possible fix is to have the cannon always go to the box on a UIM instead of the inventory?
