This has happened to me a few times - at least twice with single hand-dealt boards, and once with an entire set of duplicated boards that had been used six months earlier. In all cases the director ruled as Robin suggests, but without making any announcement.
With the duplicated set, the recollection didn't seem to help me much - I kept recognising the problems, but couldn't remember what the successful action was. I don't think there was a single board where I actually had UI at the point that I needed it.
I agree with Robin that the director should be pragmatic about this sort of thing. People go to clubs to play bridge, not to accumulate artificial scores.
When it happened to me we were fortunate/unfortunate that the board was the most memorable from the previous session; my partner put down the dummy after an auction something like 2H - X - P - 2S - P - 4S - AP with the comment "Let's see if you can do better than last time we had this auction". I quickly realised that it was the hand we had discussed the play of on the drive home the previous week, and proceeded to announce "It is that hand, she (pointing) has the K
♣ and I need to eliminate the red suits and endplay her... Director!". We tried to play the next hand of the 4 board set, but realised after the auction that it had also not been shuffled.
It was a multiple teams and we received the board halfway through the movement, so while we dealt 4 spare boards and used them for our match, every other match had already played the board. I agree that there was no decent solution other than to let the rest of the matches carry on, but I was surprised no-one else in the room (most of whom would have been there the previous week) had noticed this set of 4 familiar hands travelling round the room.
