Major Collision Issues With ProBuilder Objects

Hello,

I'm using a simple UFPS controller and I've had some major collision issues with ProBuilder constructions.

I've contacted the developers of UFPS and have found the issue is on the side of ProBuilder as the same problems occur with a standard object with a rigidbody.

When jumping onto any convex edge in a particular way the player (or seemingly other objects with a rigidbody) get stuck as shown below.

Occasionally when falling from a jump the player will just fall half way through the floor and get stuck, similar as above, but just randomly on a flat floor instead.

The UFPS developers describe this problem as "the grounded check isn't able to detect the collider until the character is already through the object" and "the mesh collider isn't being generated properly."

Why is this happening and what can I do to fix it?

Thank you.
