NL Night Club Lights borked... why?

[KLGFCG]

I don't use the nightclub lights (the spot lights that swirl around and the round disco ball-type one) often, but somehow, I've managed to screw them up. They cause hanging at the load screen if they're used on lots and have to be deleted via testingcheatsenabled and if they're selected with testingcheats on they throw up an error log (attached). HELP.

Cannot reproduce error. Clearly, this is the work of the Non-Awesome.

Are you perchance using Numenor's updated Smart Lights as well as the FFS commlightson or poollightfix? Conflict.

Thanks for the replies. Through process of elimination, I tracked it down to a file by SnowStorm (not sure if I got it from MTS2 or Eclectic Sims)... SS_Night_Light_Sqr_Mesh. Don't know what it did but it seems to be fixed with that file deleted.
