That's an interesting quirk. But I just had it happen today, and I didn't add any FAs. I changed my pitchers in the morning and saved the lineup. And checked it later. Yet at game time the line up reverted back.. I understand adding players to your team can screw up future line ups.. But when then change the lineup and save it, that should end the issues, no? Have a good one.
And then, when I view my team later, the guy I put in line up (and saved) is in the bench. At first, I figured it was my mistake. But numerous times this has happened since.... I check and double check and triple check my lineup, and make sure it is saved.... But still have had this happen to my line ups.... I posted a message in my league, and others say the same thing happened to them.... Any ideas why?
