Prop Painter 4.0 + PaintUI

Prop Painter allows you to paint props. It's like Painter, but for Props, so it's Prop Painter.

PaintUI, which is a key component of this mod, is a Move It extension that allows the current Move It selection to be painted if you have the corresponding painting mod (this includes buildings and props only at the moment). If I ever have time, I would love to add functionality for trees and networks, but unfortunately I do not have time to add these changes right now.
Recommended Mods for PaintUI include:
Painter or Repaint (use only one!)

It's in the Move It "More Tools" menu (the upward arrow). It should be at the very top. If it's not there you haven't enabled the mod or you're using an old version of move it.

All of my mods.
81 Tiles
Move It (obviously)
Painter/Repaint
And more!

Boformer for answering tons of stupid questions from me
TPB for giving me color picker code that worked (and the original painter mod from which I took inspiration)
Quboid and kjmci for testing the mod
hydra and deeheks for ideas on mod button placement
pardeike for creating Harmony which I rely upon entirely for the existence of this mod

You may have subscribed to a mod or asset ingame, or created a custom theme mix (which dynamically creates a new mod ingame, thereby triggering the reload function). I am working on a solution to this problem and will try to push out a fix sometime soon.

To those who are coding-inclined: I believe the cause of this issue is the game trying to load serialized data while the game is running (causing a nullreference). Hypothetically, this will be a very simple fix- simply adding a check to make sure that data is not loaded over existing data should do the trick. Unfortunately, this does nothing for saves that are already corrupted. If you know of a solution to this secondary problem, please tell me in the comments. Thank you!
