What gameplay feature is this bug affecting?
Cave Slots and GB

What's the issue? Please include any error messages you receive and as much detail as possible.
I bought one cave slot for 5 GB. But it somehow bought a second cave slot after I went to the trade center. I only clicked the button for the cave slot one time. I even checked to make sure I have 4 slots before I went to the trade center and I did. I had 6 GB left but then when I tried to buy this other item for GB it said I wasn't able to afford it. I went back and looked again at my cave and somehow in the time I bought the fourth cave slot until I tried to buy the trade it bought a fifth cave slot on its own.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?

Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
I clicked on the cave slot to buy one. I clicked on "buy" only one time and I double checked to make sure I only had 4 cave slots. I had only four cave slots like I needed. So I went to the trade to search for something else. When I found it, I tried to buy it and it said I didn't have enough I had 6 GB before I tried to buy this item at the trade center.
