I boost my diamonds to finished it.
I have checked the database and I see that no diamonds were deducted from your account during the 13-15th of February. Also,
Also, I see that your Combine HQ neither gained nor lost levels during those dates.
This means that the upgrade (if it was done during those dates) was never completed. This can happen in case of an unstable internet connection when the request does not reach the server and after the game is refreshed, it looks like the upgrade wasn't completed at all.
If it happened in a different timeframe, please let me know.
