Sry if I didn’t make it clear, the vessel isn’t floating upwards or anything, everything works normal except the vessel isn’t positioned right on the runway/launch pad. This problem also occurs on EVA (see link). Graphic details are set to their highest level, and I only have installed the following mod, no FAR or tweakscale (everything via CKAN):
-Kopernicus
-KSC Switcher
-Module Manager
-Real Solar System (incl. 2048 textures)
