For some reason I cannot claim the cards for unharmed win and within time limit at the portal. This happened today after some update. I did all missions with 3 stars. It just says "You must complete this and this to claim your reward".
I'm having same issue, uninstalled and reinstalled, no fix.
The game also lags sometimes when playing offline, especially when im using tower to freeze enemies, i dont know if thats related though.
So I went to redo some of the missions and the unharmed one unlocked... Is it a visual bug or something?
