The Case of the Mysterious Exploding Engine

[Stevphfeniey]

Right, so I'm building a ship that looks something like this:

As you can imagine it's going to be a pretty decent size (those engines are 3.75 meters, for those that are unfamiliar with KSP Interstellar) and I'm pretty damn proud of it. But I have an issue. I'll send that central truss section up to orbit and it'll be fine, I'll go and dock one of the engines to it and it'll be fine. Now here's where it gets interesting, I'll dock the second engine on there and it'll be fine for a bit. However after some time (be it saving and going to sleep and coming back the next morning, or launching the next component up to dock) only one of the engines will start to randomly vibrate then explode, with the other following after another save.

Debug console doesn't say anything but "Structural failure on connection between Fusion Reactor and Generator". I've got a fair amount of other mods, but the ones I have on that particular vessel are KSP Interstellar, RemoteTech (just the parts without remotetech.dll because I don't feel like setting up a comms network in a sandbox game), DMagic's Orbital Science, MechJeb, and a neat station parts pack I found on Curse that I'm forgetting the name of at this time.

Also, another interesting thing that happens is after I dock the second engine unit (both of which are the same mass), the camera focuses not on what should be the centre of mass, but a few meters to one side or another.

Anyway, hope we can figure this out together. If you need more infos or clarification, please feel free to let me know.
