Upgrade problems from V-Ray 3.60.01 to 3.60.02

After upgrading to the newest build (3.60.02) I noticed that non of the geometry in all of my render files is rendering. The only thing that shows up in the render is the lower half of my environment map.

Have anyone encountered a situation like this before?
I tested it on 3 different computers at the office with multiple files that were not altered after the upgrade. All with the same result.

EDIT: solved it the classic way - by exporting all geometry to a new file and copying the .vropt settings. However I still do not understand what the problem was.
