Previously if I had a hollow model I could zoom into the interior of the model to make sure everything was copacetic inside. Now you can only zoom close to the exterior of the model with a hard limit. In my case it's a rectangular model with hollow interior. I don't know if this affects other more complex shaped hollow things.
Hmmm, not sure if a bug, or intended... I'll move this to suggestions and see if this was intentionally changed.
