Known Issues

If paused in-flight, switching to Mission Control causes the loading screen to hang

Workaround: press '>' to resume time

Orbit Surveys are difficult to run on small celestial bodies

Workaround: geostationary or big elliptical orbits should allow the player to run those experiments. The intention of this part is for it to scan the regions underneath the vessel as it moves over them - however right now it pauses when a new region is encountered, something that occurs a lot when moving fast over some CBs. We are internally testing improvements to this so the part can get its data with less babysitting

Miscellaneous text issues in missions, i.e. debrief text repeating

Significant amounts of text went into this update, so of course a few things slipped through the cracks. Even if they're minor, please do report them!

Separators below a root part will cause improper separation causing loss of control

Workaround: Consider using decouplers instead of separators if you are running into this issue

Solar panels are sometimes blocked when in Jool's sphere of influence even when Kerbol is in clear view

After staring at the sun from Jool's 'surface', black dots may appear and persist even when transitioning back to the KSC

Surface-attached lights don't turn on properly when launching for the first time


Common Workarounds

If you run into an issue, the first thing you should try to save and reloading. We have found many common issues to be quickly fixed using this method. You could additionally try reverting to launch.

Performance may degrade over very long play sessions, but restarting the game client should fix this.


A Note on Heat

It's important to keep in mind that the Part Heat system in KSP2 is different than KSP1, so do not expect parity in this area. Tuning the numbers for the heat system will be a long-term project, so feedback is appreciated!
