Summary
Bugfixes "Fix crash when installing vehicle parts on empty square"
Purpose of change
Wow, cpart is not always a valid reference to determine a part location. So it's really not a good idea. (The additional crash seems to occur reliably after installing and then removing a part on an empty space, although on my very first try it crashed the moment I opened the install menu. In any case we need to not pass bad data)
Describe the solution
Let's use dd (rotated twice) like the entire rest of veh_interact does
Describe alternatives you've considered
Testing
Compiled it, mucked around with vehicles for a bit, couldn't reproduce crash and could always install vehicle parts when I should be able to.
