I'm having the same problem. As soon as I touch the atmosphere of Sarnus it goes to full pressure and instantly incinerates my space craft making aerobraking impossible.

The way I've been able to get back from a 150km x 150km orbit with a space plane is set the periapsis to 48km and re-enter the atmosphere with the nose pitched up at 40 degrees.

Nathankell what add on are you using to generate those beautiful clouds?

Bug reproduction steps: 1. Load KSP with realism overhaul MOD and start career in sandbox mode. 2. Go to the VAB and load my Saturn V Spacecraft. 3. Ensure that the root part is the MK 1-2 Command Pod (press 4 and click on the part below it, then click on the command pod) 4. Ensure that the crew are in the command pod in the VAB (3 crew in the command pod, 0 in the lander). 5. Click the launch craft button. 6. Craft breaks up on launch pad as soon as KJR 3.0.1 stabilizes the physics. The craft file for the space craft can be downloaded at https://www.dropbox.com/s/v46mtenr5s...20V.craft?dl=0.

If I make the same engine cluster the root part in 3.0.1, its a 50/50 shot of the bug occurring while a 100% chance if the command pod is the root part.

I am running into the same issue. I am running KSP with Realism Overhaul, Mechjeb, Kerbal Engineer, KWRocketry and FASA. All Mods are the latest version downloaded yesterday and manually installed on a clean installation of KSP. Pretty much my rocket breaks up on the Launchpad as soon as I load it from the VAB. I can only sometimes launch if I place 4 launch clamps on the first or second stage engines but its a 50/50 chance. If I quicksave and revert, the rocket always falls apart when I load the quicksave. Its a fairly large recreation of the Saturn V. The craft file can be downloaded at https://www.dropbox.com/s/v46mtenr5sroez6/Saturn%20V.craft?dl=0. I am at my wits ends trying to get this thing to launch and I think the issue relates to KJR since the breakup happens right after the KJR message shows. The rocket always separates at engines with both the 1st and 2nd Stage engines falling off.

Will keep using the old version of KJR until the bug gets fixed.
