Yes i tried it!
On the other models i needed only to align one direction and the other ones also matches. I was a bit confused on this one to see that in two directions matches and in the other ones don’t.
This may not be related to what you’re seeing, but I know the collision box can be sensitive to the region origin. Specifically, you have to be careful in defining model origin and region origin so that the region origin ends up exactly on one of the vertices in the world grid. In my experience, messing this can cause problems similar to the rotation issue you saw.
