It happened again, this time with a lighting error happening in all my neighborhoods. All the lights are flashing blue. I tried removing recent lighting mods and CC that could be the problem, but it still won't go away. I also tried the "WhatCausedThis" machine, but because it's a texture error, it can't show me what's causing it. Anybody got ideas?

Why are there black squares? Do you have a shadow problem?

Have you tried running without any mods?

It looks as though you are using hood deco that is slaved to something. Maybe Lowedeus' defaults of Criquette's streetlights?

I moved "DEFAULT_lowedeus-criquette-LODmaxisStrLght" out of my cc folder, and it worked. No more flashing blue soup. Likely I didn't downloaded it right. At least the blue flashing is gone. Thanks!

That default requires Criquette's streetlights to be installed, and also Criquette's Better Nightlife mod.
