I'm playing with RSS and RO, with the dependant mods and some of the packs like the Soyuz/Salut ships. Today while I was trying to recrate a Skylab launch I encountered a problem where the Skylab would detach from the rest of the Saturn V rocket while in vertical ascent when hitting 3km in altitude. The Skylab would just fall off the ship and tumble back down to the KSC. The Skylab is the independent skylab mod. I've tried several different decouplers, different structures, different struts but cannot seem to fix the problem. I've restarted as well, I dunno what to do.
Any suggestions would be appreciated, cheers.
