This didn't happen to someone I know personally, so take it for that. But a long time ago I was running a dungeon and someone went LD. Their buddy in the group said that his subscription ran out and he is trying to renew and get back in the game. Ended up taking a while so his friend said to go ahead and replace. If that was really true or not, no clue, and also no idea if his subscription ran out that very minute, or if there is some of delay for a few hours or so first.
