It seems that when I scout my opponents 10 plays on offense or defense and then come back to review a few minutes later some of the plays are 'unchecked'. Even if I load recommended and let my coaches choose which plays to scout they still randomly disappear, some remain checked and some dont... Any ideas?

Thought I was crazy but the same thing is happening to me.

Are you using the preview interface or the old interface?

Preview

I was using preview but switched back to old version and appears to be working now, so it must be a bug in newer version?

I noticed that the game plan in one league is thrown off when I edit the game plan in another league. It also may be occurring when I edit the run/pass settings in the defensive game plan. Right afterwards, I notice the defensive plays are completely erased. I currently can't edit game plans for all 4 leagues.
