This occured after i had deleted a .dae file in a folder i called bkup (backup) and was replacing with a newer version of the file. Now this has caused a mega problem, The chassis is duplicated BUT the Duplicate has no collision or parts on it, any ideas on a fix? --- Post updated --- Thats a bit strange... Its fixed, i needed to CTRL+A in blender and reset the chassis transform to 0,0,0
