Halo 3 Forge Issue

so forge for the most part is pretty good but when I spawn vehicles or some of the bigger objects it will end up flinging me across the map and killing me.

Also sometimes when going into the new menu for the objects it will lock up and the only way out if using a controller is to hit the escape key.

Just wondering if anyone else is having these issues

I would double check the known issues list but I believe these are already known
