Why do my MK2 Spaceplanes no longer work in 1.4?

[metzgerov]

Title says it all. After 1.4 my Mk2 spaceplanes can get over Mach I in atmo when they would hit mach 4. Also the thrust seriously drops the higher I go on air burners.

 

I didn't see any changes to those parts so whats the issue?

Someone a few threads below this one had the exact same issue, and he said “Turns out it was Kerbal Planetary Base Systems”. 

So do you have the same mod installed?

All you *should* have to do is remove the Planetary Base Systems folder from your GameData folder.  Module Manager should fix the physics config file on your next complete restart of the game.

At least, that's how it works on my system.

But then my bases will disappear I imagine right?

Sadly, yes. 

I ended up reverting to a save from roughly a month ago to mitigate the damage.

Try to see if it is different when you launch from hangar instead of reverting. This has showed up in my (1.3.1) game, and I run KPBS as well.

@metzgerov @MechBFP @pquade This bug should be fixed in the latest 1.6.2 release of KPBS.

It was due to the stock Module 'ModuleAnimateGeneric' that animated the light of the central hub but did not find the animation. This for whatever reason messed with the physics. 

If you still have the problem with KPBS 1.6.2 please let me know.

It appears to be working correctly now.  All of the testing I did with the previous bugged version now show results as expected.

Now that the cause is known, the thread has been moved to Modded Support.
