Kerbal Space Program

if i launch a craft with a structural fuselage or a MK1 liquid fuel fuselage attached as the main root (either as the first part or by selecting a new root with the root tool) and then reverts the flight to launch the fuselage changes size to become smaller changes size.
*parts attached will stay attached in their original position hovering outside the fuselage
*hitbox will also shrink to the same size
*it does not matter if i launch from the VAB or the spaceplane hangar
*it also occur if you load a quicksave instead of reverting to launch

I can reproduce this bug on all crafts i tried

Steps to reproduce
*go to VAB
*select a structural fuselage or a MK1 liquid fuel fuselage (place as the first part)(you might want a part to compare for size any will do)
*launch
*Revert to launch

the bug does not hinder gameplay because you can still fly all crafts normally even with the smaller part, although it looks ugly

i have been experiencing this for a while did not know what happened but if you re root the craft everything works fine

im running
*ksp version 0.90
*win 7 64-bit
*running game through steam

this is how it look before i revert to launch

this is how it look after i revert to launch
