The creator has been having a lot of trouble with this - apparently urinals dont recolour. Nor do they have a real dirty state as they were made to go on community lots only - and base game community lots reset. OWNED ones don't reset - so as of OFB - but it seems maxis missed updating the urinals on OFB.
EDIT TO ADD:
* leefish cuffs trout for putting a GENTS TOILET on the front page......
Argh for sloppy Maxis work making things that much harder for creators. (And now I'm wondering what would happen if you cloned a toilet and then edited the socks off its BHAVs, or just swapped them with the urinal BHAVs... I'm going to have to check that - just to try to satisfy my own, insatiable curiosity, of course. )
