... when going back to the vessel from tracking station or use "revert to launch" makes KSP use the base, not rescaled, mesh ! Look similar to this TweakScale issue, as I guess TS just use code to play with rescaleFactor dynamically. What I got is a mesh of base size 1.25m diameter, use RS to 0.5 or 2 to fit 0.625/2.5m diameter parts, it works on the VAB/SPH, works fine while keeping the vessel launched on play, but KSP messed up the size when going back later. Anyone already encounter this ? A
