Sounds like Kabam has not added checking to their server-side code to detect broken parts. What is actually happening here is you are upgrading broken parts. Normally the client would stop this but it looks like the server does not. You can test this by opening several windows at the same time and choose upgrade on each. No need to go crazy with the clicking.
