Exploding clipped parts on physics load

[EnterElysium]

I don't suppose anyone knows why clipped parts in the VAB spontaneously explode upon physics load? I'm completely lost. Seems be most aggressive with Interstellar parts. Driving me nuts.

NB: Didn't know the best place to post this but seeing as it is a niche issue with just one mod in particular I felt Dev. section would be the most knowledgeable. I have tried removing plugin to check if that is the issue - nope.

Could it be KJR..?

Parts on the same vessel don't have collision enabled. However, if the part breaks off, then all of a sudden collision activates, and the vessel telefrags itself. Basically, it would break either way since the part already has to break off for that to happen; there's not much you can do besides building a better design.

It is definitely self colliding - as soon as it loads into the scene with physics the debug tells me which parts have collided (and unbreakable joints makes it fight like there is no tomorrow, so somehow the parts are interacting). Even when welding them together using the weld plugin I still have some issues and short of welding the entire ship I cannot see that as a solution. Is it possible that the IS parts are enabling collisions within the ship for themselves, without a plugin required for that? That would be mighty odd.

Perhaps it's due to some strange plugin-caused thing involving particular parts? If you're using the welding plugin that might be causing some issues as well since that might interfere with disabling collisions; as I understand collisions need to be disabled for each collider and if a part has multiple colliders that could be the issue.

I only put the weld plugin into the mix afterwards to try and solve things (the welded parts do indeed stop clipping with each other) and when I pulled the plugin the parts still behaved the same way so it must be related to the pasts mesh or the cfg... but I have no idea how either of those could override the no-clip function! Definitely does seem that two parts in particular are causing issues (2.5m AM Reactor and the Warp Drive 2.5m), I'm going to duplicate them and strip the cfg to see if that helps.

Edit: None, duped parts with stripped cfg's still have the same issue, it must be intrinsic to the mesh itself...

2nd Edit: After stripping cfgs seems it now works... not sure why there were issues... but it works. So I guess its celebration time!

I've had this problem before. I think a joint did break, and that allowed the self-collisions to happen. All it takes is one little piece somewhere and your ship is Kraken fodder.
