Constructor difs crash Torque when used with vehicle collision

Just wondering if anyone else has experienced Torque crashing when a vehicle encounters a "constructor made" dif? This happens to me everytime. The dif imports fine but as soon as I get a vehicle about to collide with it, Torque crashes. I've tried exporting several Brush types (collision, vehicle collision, structural) but haven't had any luck. So, I'm back to using 3d world studio for these types of objects. I'm using TGEA 1.0.1 with the Legacy TGEA DIF exporter. Is there a known issue with this in constructor? Could this be an issue with how I've built my collision box? So far, all objects exported with map2dif out of 3d world studio have worked great. Any help would be appreciated.
