I have since solved this by wasting tons of coins and time getting other cards for the set. The issue is if the card was UPGRADED at anytime, meaning even if it was done by the prior owner who sold it on the auction house, it will throw this error out on any set.
From reddit I have not looked into this, but it could help ya'll troubleshoot
Idk if anyones been having their 92's crash when trying to add 90's or not but ive been able to find a workaround that works for me and could hopefully work for others.
What ive just done twice is if a 90 for some reason either wont be recognized to be put in a set or if it is recognized but crashes me to the main menu i can post it to the auction house and pull it right back out and it fixes it. Hope this helps anyone with this issue.
