Yes, i already staged them, they blew up, flew away but the tanks remain stuck to the ship. build is simple, take an FL-800 tank, put decoupler on (in any way... i've tried it all...), everything seems normal but it does not decouple, as you see in the picture there is nothing connecting the parts anymore but still they are stuck together.
Thanks! I will do that... My KPS version is 1.2.0.1586 (which should be the newest...), also in the picture i took.
Edit:
okay after reading this:
Im using steam, 64 bit win 10, version 1.2.0 of the game, and i havent yet figured out how to find the output log.... and im running no mods or anything...
