Rocks'n'Diamonds

Hi all

On a 3-player levelset, I'm suddenly finding that players 1 and 2 look like the Boulderdash(?) characters whereas 3 and 4 look like the R 'n' D players. They used to all be the R 'n' D style players but I can't work out how to change this back. Any help would be much appreciated.

Best wishes

Are you using any custom artwork set?
Does the problem persist after a restart of the game (program)?
Could you make a screenshot of this problem and attach it here?
All in all, this sounds a bit strange indeed...
