Its not @SQUAD's fault. Its more so on the porting company to iron out these issues.
It never has. No game is perfect. Like I stated above, it is partly the porting companies fault. KSP is developed by SQUAD, and the final products are sent to another company for the porting to consoles. Sometimes this transition isn't smooth, o we end up with a couple major bugs for a few months. And I can gaurantee that the company contracted to porting the game has other projects with higher priorities than a port.
We are only 3 behind, all we are missing are the 1.8 1.9 and 1.10 updates. And that tajes time, because the porting company irons out other bugs in the process of making new ones by accident.
I like all of you here am not super happy about the game's state, but all in all, it is a game, so when you bought it, you accepted the fact that it was going to have bugs. SQUAD isn't Activision, or Treyarch, Bethseda, or 343, so they don't have a team for everything, with that being said, they have to contract companies to help with that, which takes time and money. Relax, chill, and wait patently like everyone. And don't DM the Devs asking for fixes, instead throw the bugs in the tracker
