Crash to desktop on staging

[DonaldPK51]

SO I had a launch vehicle that worked fine, for a basic Mun base. After a bad landing, I made some adjustments to the lander itself, but left the LV alone. For some reason, the game crashes completely now when I stage the first time (stage to fire first engines and release clamps is fine) and I can't seem to get it fixed. I even deleted the entire launch vehicle and removed all the staging components from the lander, and rebuilt it from scratch, but it still crashes as soon as I press space to ditch the first stage engines.

1.0.5, Steam, Mac. No mods at all. The game itself seems to function perfectly fine otherwise, though I haven't tried launching any other vehicles.

Do you use the big 3.5m decoupler to decouple? That causes a crash on Mac and Linux if you combine it with certain parts...

[DonaldPK51]

That would be my luck! Yeah, 3.5 separator with a Rhino. Worked with the mk1 design of the craft, one of those "certain parts" must be on the mk2 version, since it worked before.

Back to the drawing board for the LV I guess, thanks!

Why does the 3.5 m decoupler cause a crash? Also, what are the ‘certain parts’ for future reference?

Somewhere in there: http://bugs.kerbalspaceprogram.com/issues/5414

Basically, the big decoupler causes an exception on decoupling, which Windows handles different than Linux and Mac OS. You can add  "PhysicsSignificance = 1" to it´s config file and it wont crash, but since its a workaround, i try to avoid it.
