Swat 3 GOTY Crash: Attemp to access invalid polygon

Hi fellow officers.

My game crash for some reason in some levels. I'm limited for a few maps only. The attached image appears after crash. In my opinion it is a character/prop mesh.
In this case I've been using the "BlueLight" Mod. I don't know if someone had this problems. I've been using the last beta version of Last Resort.

Thanks
(If image doesn't load the image pop up says: Attempt to access invalid polygon: skin=m1a_s*02811, index=-1,#tris =177)

See if it is when a swat member pulls out the m1a_s or when a suspect or bad guy or bad female picks one up. Some levels have those scattered to recover. Need more info on when it is happening to create a fix.
Map? Other mods? Would like to replicate the problem to fix.

I don't really know to be honest. The next paragraph explain how does it happen

Start Mission (Example: LA Convention Center, night)
-Mission starts
-go to the stairs
-See suspects and a few minutes CRASH with the message wrote in the first post

Mod has been updated and fixed!
its on the Swat3Reunited Site.

There were several request for this update and now its here.

To replicate the problem, use any of the M1A bluelight weapons and turn on the flashlight. BOOOM! crashes.

can't find it anywhere on that site
