Bizarre flickering problem

[Cozmo]

I haven't got much left to map for my mod, but finally bumped into that weird problem I get with pretty much all of my maps.

Sometimes, when I add several lights in one area, all the objects nearby will flicker in the editor and actually in the game itself if I leave it. I've tried zoning the areas apart and haven't duplicated any lights near the area. (Or at all, if I can remember right) No idea what's going on here or what could be causing it. I'd really appreciate it if someone could explain this to me.

Perhaps put the light radius down, sometimes I find that a lot of lights at the default cause mistakes. It's better to have a few more, but smaller, ones. Also, try with a different renderer, see if the problem persists?

Rebuild geometry. That'll fix it.

Thanks for the replies!

It didn't help unfortunately; it was still happening in game but after deleting some lights and zoning more areas the flickering decreased a bit BUT it seems like I don't have this problem with beams or cagelights, oddly. Even when their radius touches the objects that flickered before [being in the radius of lights was starting the flickering]. So I've been using them when I get this problem and it seems fine now.
