All of a sudden I cant choose cards after a mission except for basic cards. My party has completed every mission already.

It was working fine before but now i only see basic blessings, weapons, etc... Any fix?

It happens to me too. I can just say that if you are playing Story mode, only after AD3 scenarios I can see cards other than basic. Also some cards seem to have a maximum number of instances. So if a char has already Flaming Mace for example, it simply doesn't appear.

For a fix... it ll be long.. there is a full list of critical issues before that mate...
