Yesterday i collected enough crystals to upgrade my "Increased damage" module from lvl 3 to lvl 4. When i press upgrade, nothing happened except my 16-18k crystals(dont't exactly remember how much it costed then but now it shows that it costs 18k crystals) dissapeared and module stayed on lvl 3. Well i thought it is probably a common glitch and when i will restart game it will be on lvl 4. Next day(today) i opened Tanki and i see that i have one empty module slot(exatly the one my increased damage was usually sitting in) i opened turret module tab and i saw that my increased dmd module was out of slot it was before and that it is still on lvl 3....Any sollution to get back my crystals or get it to lvl 4?
