Undocking= exploding space station?

[Jhawk1099]

Hello, I have a problem. I have these rescue rockets in Mun orbit to pick up a kerbal whenever a contract pops up. But whenever I undock them the whole station explodes after a spot of lag. I can put up a video if it would help anyone help me.

Sounds like a bug. But other than that, we can't say anything without more information

I've had this happen once when a symmetry glitch in the VAB caused two identical craft to be docked at the same port (they were docked there during launch, as a multi-satellite-deplyoment craft), overlapping each other - no idea it happened until I went to decouple them in orbit, then BOOM, debris everywhere... two copies of debris everywhere in fact. Is it possible that something like this could have happened?

This does sound like a bug. Please provide as much of this information as you can.

A save file might also really help out in this case.
