i just set up scene as you described useing the default platform100 and a cube I made 5x5x5, lined up with the default. useing the fps camera. and useing the default "50" collision map resolution it crashed on contact. when I set resolution to 5 for this object it was fine and collisions worked properly. the resolution is usually the average size of the triangles that make up your collision models. I usually use setting between 1.17 and 5.17.

Please try removing the base (floor) of your house.

Collision detection models do not have to be closed hulls (but see edge consideration in the official modeling tutorial, RIGID-BODY MODELING REMARKS section).

Aligned surfaces (the floor and the flat ground in your case) create a configuration which is not recommended (see tutorial above, at 2., RIGID-BODY MODELING REMARKS section) because it confuses the collision detection system and may cause missed collisions and crashes.

Cheers guys, sounds like I'll be able to figure the rest out.

Can you upload the meshes for reference?
Have you checked the polygonal collision meshes for degenerated triangles?

The one I was on about was just a simple 4m x 7m cube, 6 faces in 3ds max.
