Yeah, unfortunately our Scons seems to be too old for the updated build in godot 3.5. It works if I update Scons to >= 4.0.0, but I'll have to check that other Scons builds aren't broken by this update (last time we did even a minor update it broke several builds).

@Staudey, I updated scons to 4.4.0. Updating godot shouldn't be an issue now.

@algent Cheers! Worked like a charm with the new scons.
