I opened up a support ticket for this. I was using a roster that was missing some of the 2 way contract guys. I used player dna to add them to Fa pool. They appeared. When I clicked on them to sign them and edit their contract the game froze and I could never get to edit menu. This happened many times and on a few diff rosters. 2K said to clear cache and then send them a video. Have not done either yet, assuming cache thing is useless
