So... Apparently you can't save jets?
I stole the Fighter Jet from the military base (after a few failed attempts, man it takes ages to get in the cockpit, flew it to the hangar at LSX which I have purchased as Michael and have a Luxor there. There was no option to "enter" or "save", like the garages have. So I just parked it in the hangar. Walked a few feet away and when I turn back, the plane was gone.
Cool, it saved. I go to check. GONE.
Serious? This whole garage system is worthless, everything is a hit and a miss.
EDIT: And wow. Wrote this after it happened, had dinner. Booted up GTA again. There it is. Wut?
Alright, so... How does this garage system work, is there a delay of some sort? I guess it works for planes. Pitty cars still don't save sometimes.
