I'll make some changes and test, but this does not explain why this only happens when the MJ addon is flying my ship, and not me. As I've mentioned, aside from adding more struts (the ones strapping it all down up on the upper section) and the MJ part for MJ to work, I have this exact piece already in orbit. So something is not working like it's supposed to. Be it the addon or the engine running the addons interfacing with the underlying Core. The thing should work either way, if it's not going to work. I mean I get that "**** happens in space" but this is happening consistently. I can consistently stage the entire thing to orbit manually, just not very well. I enjoy making the rockets more, which I why I was so happy to see this addon (it's also why I purchased the game, otherwise I would have just stuck with the demo and eventually abandoned it when I got tired of building things). Also, my nose cones are popping off before I even hit the ignition switch. The struts should have a note saying they de-couple on their own. This is an issue with the underlying game I'll eventually be bringing to the devels. The parts aren't always described with enough detail. They've spent more time trying to make the parts "fun" and "quirky" in the name and description and no where near enough time making them comprehensible enough for someone to be able to sit down with the game and have fun building on day 1 (unless they only planned on people playing the game who are also NASA engineers). The Wiki is not helpful often in this respect either. OSS games can sometimes be plagued with this issue, but more often than not they're documented even better than this one is it seems (though my experience with OSS games is fairly limited, my experience with OSS software is rather vast, so this may be an issue of quantitative vs. qualitative data, but still, I bought the game, I expect thorough documentation). This is a digression though, and has very little to do with this MOD.
