Kerbal Space Program

First of all I have to say thank you for making this game it's amazing... Alas every time I play it the same issue happens I played early pc days got really into it playing the early science builds and there was an update that broke the save. Now I got REALLY into it again on PS4 cause I love the game and purchased on a whim to support the game.. Anyway the game has been freezing all day on me.. Usually when building a ship 40+ parts eventually just started saving the ship more often. (that's another issue in itself that I figured I tell you about.) I got past that by saving my ship every ~5 parts. But I played a bit more got a research station around Kerbin and the Mun and fast forwarded a bit for some juicy science.. Just bought drills backed out went to the assembly complex and built a small like 4 piece ship realized I might need a docking port if I wanna build a refueling station and pushed the back out to the map button froze for like 2 seconds and playstation gave me a crash screen I figured it was a regular crash that just happens time to time (because it being a early pc port.) But I started up the game again and it said save is corrupted do you want to delete? (I selected no) ran game hoping i could just flash a quick save like on pc but no it was only the persistant quick save... If you could fix this and find a way to fix our saves it would be very appreciated.. Sorry if I sounded like a ass hat at all, I love you squad dont hate me you made one of the best games ever, if that helps :P anyway feel free to contact me for any more info, game testing, or anything really. Thanks.
