Kerbal Space Program

What happens:
When using launch clamps, the ship is subjected to a severe force when transitioning to the launch pad. This force can cause launch clamp failures on ships that worked just fine in 0.21.x. In the debug log, there is a "Ground Contact! Error = xxxx" message. In 0.21, the error was 0.006m, which caused ships to wobble a tiny bit. In 0.22, the error is now 0.141m, and it can break launch clamps.

• Create a ship - I've used a Mk1-2 command pod, two Jumbo-64 tanks, and a Mainsail engine.
• Attach two launch clamps towards the lower 1/3 of the bottom J64 tank.
• Launch. Notice the ship is jarred pretty severely. Usually, a launch clamp fails, although even if it doesn't, at least one clamp will be vertically displaced.

Notes:
Clamps do not fail with smaller / lighter craft. Ship / clamp configurations that are stable in 0.21 can fail in 0.22. Fails consistently with some non-stock parts (for instance, KOSMOS URM L09 1.25m fuel tank). Can work-around by hacking the launch clamp to a much higher breaking force (I am using 1500 instead of the default 150) and strutting the ship to the launch clamps.

Can the joints be made unbreakable during the scene transition, and then switched to normal behavior after the ground contact corrections take place and the physics effects settle down?

Found on Win7 / Steam installation, verified on a clean install of KSP (no mods). Leaving priority at "Low", since I don't know what criteria apples for changing priority.
