As the title says, Kerbal crashes when I reenter the ship after unlinking any of the pipes added after docking. It doesn't matter which pipe I unlink, which kerbal does it or in which module I enter.

Attached you may find kerbal dump and logs. My window locale is spanish and so some errors appear in spanish, I can help translate if needed.

It looks like a mods conflict issue. Try removing all mods that you can to not break the save file, then try reproducing the issue. Alos, I need KSP.log file (it gets overwritten each time the game starts, so capture it right after the crash).

You are right: I've removed everything but KAS and module manager and now it doesn't crash. sorry to bother.

FYI. If you could figure out which mod causes the conflict I may try fixing it.
