I know the current Paul (the ones who all the girls seem to like) directly replaced funny Paul, is this the only time when someone has directly replaced someone with the same name?

There must have been a lot of other occasions when this nearly happened. On the days that "Mark W" and "Nick M" played, I thought "Didn't realise there was another Mark/Nick!", but that was becuase Mark A was the new player in Mark W's game, and Nick D was the new player the day before Nick M played, and I hadn't noticed him!

Does this scenario occur much?

That's not a reflection on the player, BTW, it's my fault not recognising them until they've been there 3 or 4 games, especially if they open their boxes in quickies, unless they're a real standout charachter like Lance or Melanie!

Wasn't Paul replaced by Lindsay?

Andy Kelly was replaced by another Andy.

and

Mark W was replaced by Mark A.

Michael C replaced Andy K

All wrong I'm afraid!

Someone needs to edit Wiki!!
