Since the last update i can't see the paint on my large storage box for example. The paint is still there when i check with the paintbrush. If i paint it again i have to leave the area and come back to see the color. But if i quit the game, it's gone again.

Confirmed, spray gun does not work on metal structures, tried different spray guns, different dyes, nothing. It painted a wooden sign just fine but none of the metal can be painted by a spray gun nor a paintbrush.
