Kerbal Space Program

Confirmed, with a similar craft, attached.
As a temporary compensation, players can reduce 'Convection Factor' in alt-F12 settings or machConvectionFactor in physics.cfg from 7 down to 1.

As a workaround, players who have 'PartDatabase.cfg' from an older working version can copy that file into the KSP-1.8.0 directory and edit to say "version = 1.8.0.2686" delete the line with "version = ..."

Confirmed with all my SSTO planes. I posted this in the forum and found others had been having the same issue.

"on re-entry the right wing begins to overheat almost immediately upon getting under 70k.
If I'm returning from LKO it survives, but remains right on the brink of exploding all the way to landing, even when stationary having landed the gauge is still there and is still over 70% of the way to exploding.
some other parts of the plane have a similar issue but to a lesser degree. the left wing has the issue but doesn't get as close to exploding as the right wing. I've messed around with the angel and whatever I try the wind or components on the right side of the screen are always hotter than the left. I rebuilt the craft from scratch in the new build I still got the identical issue.
If returning from anywhere beyond LKO (i.e Mun, Minmus even HKO) I can kiss the wings goodbye."

In combination with the drag bug(?) this breakes the game and should be both rated high.

Example:
a booster reentering from 72km at almost orbital speed when crossing 30km from same savegame:

1.7: surface speed 1.872m/s, drag 25,730 kN, convective heat 707.852.000kJ

1.8: surface speed 2060m/s, drag 11,861kN, convective heat 2.040.896.000kJ

Agree with that. I confirm this behavior.
I would also mention the asymmetric overheating, that is, the right wing on a ssto ((both ascending or descending) is more prone to overheating. I’m not completely confident with this, but I would also add that this happens when the nose is pointing above the prograde marker. If you pitch down below the prograde marker, then the “preferred “ overheated side becomes the left one.
This bug however is not only about overheating in an atmosphere, but it is probably related with weaker drag and, as such, it strongly affects two of the main phases of a mission, that is, ascending and descending. I would recommend rising its priority, since it completely breaks the game balance.

just_jim maybe these logs will help?

I was entering into the atmosphere and checked the console and found errors as the following were spamming

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Testing done. I cant get the problem to happen again. Maybe I was in 1.8.0 thinking I was in 1.8.1.
My Eve Rocket can get into the atmosphere and out again as per 1.7.3
