I finally pinpointed the issue I've been experiencing for the past two months. I picked up the Cam Jurgens AKA Icon back when it came out and had been starting him at center until just recently. When I had the card, the game wouldn't let me adjust any of my offensive linemen without crashing (which made it a nightmare to change my line or put any players out of position).
I still experienced the issue even after taking training off every single one of my cards in my binder. I haven't had Jurgens even in my lineup for about a week until yesterday when I used him in a set and completely god rid of him, and wouldn't ya know it... all of the suddent I can make changes to my O-Line again! To make sure it wasn't an issue with just that specific card, I grabbed another last night and boom... the issue returned!!
Has anyone else had any issues similar to this with Jurgens or any other card? It kind of sucks for me with a 20/50 Eagles., 10/40 AKA Icons team because I can't even use him as a backup center/guard
