Collision errors in a .DIF made with Constructor

[Aphtonites]

Every time i export a DIF using torque constructor, most parts of the shape is de-collisioned even though i ticked all the brushes in Constructor on "Collision"
Am i doing something wrong here? Or is it just Constructor?

Constructor has a very curious bug to do with collision. To fix it do this:

File -> Save your .csx file.
File -> Close Project
File -> Recent Projects -> Your Map
File -> Export Legacy DIF

And it'll be fine.

Ah, i forgotten to save a CSX file for it
