I'm having a bit of trouble with the new patch, it seems that the manned 2m starting pods mass varies. It should be roughly 10t but when parts are added (can be anything added after or putting a pilot in the cockpit) the mass will shoot up exponentially. It seemed any time an object updated it added 40tons removing the supplies inside the pod also raised the mass. Workaround i used was to add the capsule last and save unmanned and man it on launchpad, however it seems that it still calculates the wrong mass on the pad (but will allow it to launch) with mechjeb registering a 5.0 twr i couldn't lift at all with over 400kn of thrust.
