No exp needed for Kerbals in 1.12.0?

[B94]

So I started a new career game together with this new update. On my second flight I suddenly see  that Jeb can do everything from holding prograde, retrograde, to normal, antinormal... - although at that time he should be only able to do stability assist.

Is there a chance this is some kind of new bug? I started new career game many times before and nothing like that has ever happened.

Or is Jeb so awesome now that he broke the game merely by existing?

It might be your settings. I'm testing a 1.12 career game and my Jeb has no superpowers. He's only made it to level 1 and can hold current heading, prograde, retrograde. The other SAS modes aren't available to him yet.

I don't think it's the settings, I run the game on normal difficulty and Kerbal experience is automatically enabled.

I also opened a new career game and it has the same problem. I guess the next thing to try is to download KSP again...

It's this bug:

https://bugs.kerbalspaceprogram.com/issues/27169

 

A quick "fix" is to buy the Making history expansion.  I expound on the issue in the linked issue report, but I'll copy it here for the record:

This problem appears to only affect users who have "Making History" not enabled.

The reason I am aware of this is that I am the lead of the "Kopernicus" mod team, and I became aware of this in unrelated fashion when we discovered that disabling Making History (with the mod MakingLessHistory, which simply renames the kspexpansion) fixes our other reported bug https://bugs.kerbalspaceprogram.com/issues/26035

Unfortunately disabling Making History as we now advise is causing a large number of users to now notice this behavior.

A look in a decompiler on Assembly-CSharp reveals the issue. In APISKillExtensions, the entire class evaluation for skills is shortcircuited to true if this returns false:

if (ExpansionsLoader.IsExpansionInstalled("MakingHistory"))

I would suggest a more sensible branching evaluation structure.
