Struts/Fuel lines clipped inside of parts cause craft explosions
The new strut/fuel line models cause physics to freak out and or explode upon vessel loading if the strut (I believe specifically the second end placed) is clipped inside of another part.
Attached is a simple 6 part craft with a central fuel tank, that has smaller tanks radially attached to it. the radial tanks are then gizmo'd in to allow struts to be places so they are inside the model. If this craft is loaded to the flight scene it will explode. If you delete the struts and launch the craft again it will work just fine. Fuel lines appear to do similar, though sometimes not quite as aggressively.
This also means that any craft in existing saves from 1.2.2 that are already launched and have struts clipped inside will explode the 1st time the craft is loaded in the flight scene in 1.3, potentially destroying peoples long term ongoing saves.

I am also testing this strut thing and I have 4 fuel tanks radially attached to a srb for support and 8 struts in 4x symm going inbetween the tanks at the top and bottom of them, putting a panel flushed with the top of the tanks makes them jump through the fairing which is close to the tanks causing an explosion.

Edit: Wrong Craft File uploaded, Strut Testing.craft is the right one

Adding another note, since fairings (unless inline) are solid until you deploy them, struts now (at least with some configurations) detonate inside of fairings even if they aren't clipped inside any actual objects. I haven't had time to thoroughly test multiple scenarios of this but I did come across it this evening.
