Eventually the colours got so strong it got unplayable, removing this mod solved the problem.

Autobuild shows a square around the character when turned on to show what's in range to be built. If you're playing with long reach mod, then the highlight will cover the entire screen.

You can change the intensity of the highlight in Settings -> Mod settings -> Per player -> Autobuild -> Visual area opacity. Setting the opacity to 0 will disable the highlight entirely.

Should it be disabled by default? Or opacity a bit lower? In combination with long reach, it might be too much.

I added a setting to En-/disable the visual contruction area. This should be more obvious
