What the heck is this?

[CaelumEtAstra]

Last night, I was building an SSTO. I was ready to fly for the first time, so I click the launch button, but nothing happened. I tryed to exit, same thing. Tried to load another craft, no luck here. Every button in the upper right hand menu of the SPH wasn't working. I opened the Debug window and BOOM Null refernce exceptions for evey time I clicked those buttons.

Here's the output log

And the (suspected) offending exceptions

I would have put this in the support thread, but i'm not sure if it's a stock bug or something mod related.

I think this is a known stock bug. I don't think there is any known fix. Claw would like more details on this and what you did before it happened. I suggest you contact him.

Have you deleted any parts from GameData which were on the ship you tried to load? What you've described is exactly what the game does when it fails to load a ship because of missing parts.

EDIT: Or have you updated any part mods which have removed some of their parts?

There is a null reference exception in your output being caused by planetshine.

Also Active texture management was having problems loading MkIV parts.

NullReferenceException: Object reference not set to an instance of an object at Clouds.Clouds.Update () [0x00000] in <filename unknown>:0 (Filename: Line: -1)

You did find the problem though.

However as I am kind of a newb to this aspect of the game I have no idea what to do after I find a problem.

Also this is most likely a problem due to mods not a bug.

Looks like you are getting a lot of NullRefs from various places. Dropping this into Modded Support, where you might get some better attention. You might also want to have a look at the sticky and see if there is other relevant info to include.

Good luck,

This happens to me from time to time too. The last time it happened was after I tried to open a craft with missing parts and then edited and launched a different craft. Unfortunately, I don't have the logs as it happened a couple of weeks ago . ALT-F4ing then starting the game is the only fix I can think of.

[Master Tao]

Indeed, clear reproduction steps will be needed to provide much help here. Start with this: does this happen with every craft, or only with certain crafts? If only certain crafts, what parts or features do they share?

Can you reproduce it with a minimal set of mods?

The exceptions seem to start in the pre-flight checks for part count, mass, and size, but there's not enough information here to explain why.
