I’m unfortunately having the same issue again: mobile, Firefox, league 29 (crab drib). Trying to move Tristan Thompson into a G/F spot after Griffin, who got a DNP and 0 min tonight. Had griffin played I would be out of games for the week I think.
I’ll put TT into the spot just now, says “saved” navigate away, back to lineup, and he’s back on the bench.
Griffin should be locked into your G/F slot even if he didn’t play.
Players who don’t play a single minute will lock, they just won’t count as a game played. I’d have to look at your team to figure out more, but probably won’t have a solve until tomorrow. Link to your team whenever you can.
