Hello! Straight to business
I'm playing in ps4. Whenever I select a vehicle to launch, be it inside the VAB, SPH or choosing them from space center view, most of the times the game loads the "last" ship I've used, like if I'm tweaking a rocket and add another line of boosters, take out a fuel tank or whatever, then I save the vehicle and select launch and the earlier model appears without the changes I just made. When I go back to VAB the old model appears, but I can load the newer one no problem, although this can happen a couple more times before actually loading the right thing.
This starts small but after happening like 60% of the time it gets really frustrating having to go back to assembly, reloading the vessel, checking crew and hoping for a "hit". I lost more time than I'd like to think thanks to all of this, it gets worse when after 4 trys the ship finally loads and you discover jeb instead of bob on command.
Thankfully if the ship (let's say X2) loads right once it can't revert to the earlier stage anymore (let's say X1), but if you add any change to it, it might revert to X2 back again.
I've been looking around the forum for a bit and the internet for a while and noone else seems to have this problem so I figured I can post it.
