Hell Kraken followed by cloned kerbal when entering hatch.

[Squiggsy]

Hello all, I just had my first experience of the Hell Kracken (completely black screen apart from HUD, happens after kerbal hits the floor) and when i restarted KSP all seemed ok, until the lander I had on Duna where it all happened refused to take off (engine displayed NaN U of fuel flow) and then once i had solved that (hopped into the air to do some atmosphere science) I got out to collect the science and upon reentering the lander Jeb cloned himself, one ended up inside the lander and the other stayed outside and ended up standing on the floor outside 0.o

I have been blessed in the install up until now and experienced very few bugs, I was wondering if anyone knew of any mods that were the likely cause of this, the only other bugs I have had have been Kerbal Join Reinforcement created (docking nodes not separating when undocked and Infernal Robotics pieces not moving on large ships), The list of mods I am currently using are:

Active Texture Management

Adaptive Docking Nodes

B9 Aerospace

Community Resource Pack

Crossfeed Enabler

Crowd Sourced Science

Action Groups Enhanced

DMagic Orbital Science

Kerbal Engineer

Kerbal Joint Reinforcement

KW Rocketry

Infernal Robotics

Mod Oriented Tech Tree

Nav Ball Docking Alignment

Near Future (solar, construction, electrical)

NehemiahInc Science

Procedural Fairings

Regolith

Tech Manager

Tweakscale

Tweakable Everything

Universal Storage

any help would be appreciated since the bugs seem to have very suddenly started multiplying, which is odd because I haven't changed or added anything today or yesterday so I don't know what started it off.

Edit: ANOTHER JEBEDIAH JUST APPEARED ON THE LADDER 0.o
