Help! Micro upgrade didn't upgrade, lost crystals.

Countach 3 years ago updated by Sia 3 years ago 2

Hello. Yesterday I upgraded Viking M1 and Twins M1 to Micro-Upgrade lvl 2, spent 5320 crystals. Today i log in my account, it shows that Twins and Viking have been upgraded, but when i check in garage it's still at lvl 1 M-U. So i lost crystals and didn't get anything. Is there a way i could get my crystals back?

i've lost my micro-upgrade speed up, i've speeded it up and after the restart of the server it returned and askeing me to speed it up again, also my crystals are gone!
