In using Wizards of Simpe, I recolored the oleander. 3 days later, it flashed blue and I had to remove them. Why did they flash blue after 3 days? I re- did the color and had same thing happen a week later.
Sometimes things just randomly have flashing blue problems, or mesh explosion problems. I don't think it's necessarily because of bad CC, the game just shits itself sometimes. I find switching between live/build/buy mode or reloading the lot sometimes fixes it.
