I have been facing a bit of an annoying issue with the HX parts. When ever I use them and launch a craft they always behave with an undesirable trait. Upon the physics loading on the runway or launch pad the parts either shake themselves apart violently, don't stay together at all (fall though each other as some people have been mentioning in the thread), or oddly rotate about the cockpit (if the cockpit is the root part the whole craft leans towards it, no matter how heavy the rest of the craft is, or is the cockpit is not the root part then the craft leans back and clips straight through the runway so that all you can see is the cockpit sticking up). I don't know if its just an odd clipping issues with B9 or if its something wrong on my end. I've gotten the same issues with B9 being the only mod in the file and with B9 being with other mods. Any insight to fixing this issues would be greatly appreciate! Thank you.
