Kerbal Space Program 2 has been spamming your Windows registry with junk since launch, but a fix is being tested right now

Your Windows registry is not the sort of place you want game code to be constantly adding a whole bunch of unnecessary data to, but that's exactly what Kerbal Space Program 2 has been doing. Presumably since it launched into Early Access, too.

KSP2 cannot catch a break. It was one of the poster children for a successful Early Access campaign—after an initial independent alpha stage—but pretty much all of that goodwill has evaporated with the release of this second instalment. It's light on features, much lighter than the original game, and has suffered from a litany of performance issues.

And now a potentially system-breaking bug has been found, highlighting the fact that the game's accessing the Windows registry regularly throughout the game—when you're moving between loading a new save, or shifting between areas (planets or moons)—and writing new, unnecessary data into it over and over again.

Community managers and developers have responded in both the KSP forums and the discussion section on Steam, to say that the developers are (now) aware of the issue and have a fix. «It's currently being tested and we're aiming for a hotfix, thanks for bringing it to our attention!» is the current response on Steam.

There are many responses across Reddit and the forums, questioning how any developer could have created such an issue, with some talking about the situation being akin to the KSP2 devs simply using the registry file as a temporary data dump. Others have said it looks like mistakenly storing settings under a constant variable where it was actually a dynamic
