"loot spillover" system, save the loot D:

I hate it when all my storages are full and all my builders are working. Makes me not want to raid, because I'll be wasting loot that others could have. So I thought about this "loot spillover" system. When your storages are full, you can have a backup invisible bank to keep an x amount of resources. But, the catch is if your raided and the Raiders land on that invisible bank they take all the loot.

When raiders raid you, the available loot will look like "250,000 + 100,000" that +100,000 will be the loot spillover.

The loot spillover Is a 1x1 trap, so if you don't find it be the end of the raid you don't get it. But if you do land ON THE BLOCK IT IS (No radius) you get all 100% of it.

Thought about this?

Edit: Max loot it can hold is 1m gold, 1m elixir, 10k de. Get at th2 and there's no upgrades to it.
