Tried a new game and no problems flying multiple portals. The GIU on the hurricane is insane. Sadly it handles like a drunk bathtub.
Maybe the crash from my old save has something to do with a quest in my log or some old code from previous versions, dunno. I am going to take a little break because starting over those forced story scripts yet again, I just don't have it in me atm.
Attached is the logfile of my old save. I am flying a silver arrow make two transitions then crash.
