Currently vehicle loadouts or their positions are not saved. For example kitting out an A-10 can cost 2k+ xp and it'll be lost on a load event. They also get teleported to the carrier.
It would be nice if at least the vehicles loadout is saved so xp is not lost on load.
For position saving base location should be enough. Their placements can be random. For vehicles not at any base, closest base would be their location.
