I have experienced this bug many times with many mods.
Usually, it happens when I use the 'next target' view. The problem only seems to become evident when either the target I am viewing is destroyed (while still watching) or I am watching a target that moves out of visual range (i.e planes).
Sometimes the pivot point is off center and others the camera just zooms up & down on the spot.
There seems to be no way to correct this while in your current patrol. The only solution (for me) is to save & reload, no need to exit SH3.
