Paint STool still not working properly after 4 months

This may not seem like a big deal to most people, but the Paint STool has not been able to paint environments for the past 4 months.
The only thing you can paint on are doors, spawned props, and ragdolls. Before GM13 was released, this wasn’t a problem. I’m a poser, so this is kind of a big deal to me.
I get that there are more important things to fix than this, but it’s been 4 months. Come on now.

And I didn’t even see anything about it being fixed in Update 156. What the everloving fuck, Garry.
