Dif Collision Glitch

Well, hello all.

There is an issue there is kind of disturbing me, about dif interiors.
We are using Torque 1.5.2 and constructor 1.0.4.
The problem is, and we don't know why, some geometries we make on constructor simply don't colide with the player...but it colides with the projectile. You start to walk, and you simply fall on some floors, pass through some walls, or some geometries simpli disapear. There are no concave surfaces what-so-ever on it...

there are some limitation on the dif format that may cause this?

Thanks

Rocky
