Unplayable lags during asteroid redirect training 1

[akshimassar]

Overall description:

When I am trying to play "Asteroid redirect mission, part 1", game starts to lag after first dialog.

Steps to reproduce:

1. Start training, choose "Asteroid redirect mission, part 1", press "Next", than "m", than Next-Next.

2. "Rendezvous -- practice" dialog opened, "Next" is active. Test changing view and editing maneuvers -- everything runs smooth and perfect.

3. Press "Next", test editing maneuvers and changing view -- very laggy, almost unplayable. "Next" button would be inactive in normal conditions.

What I do to test it:

1. Choose minimal setting via game menu.

2. Temporary moved all mods out from GameData dir.

3. Set up debug log in settings.cfg to True

4. Cleaned Player.log and make standalone test. I added line numbers to identify some interesting moments. I pressed "final" "Next" after line no 6875, it started to lag, I ended scenario and closed the game.

5. View pidstat for KSP -- it eats user time, something slightly more than 1 processor. Memory usage, sys calls -- ok.

Here is Player.log: https://drive.google.com/file/d/0B9ROfAnslOdGTVlMbkRpNFdfMEk/view?usp=sharing

My CPU is AMD FX-6100 Six-Core Processor 3300MHz

You are getting nullrefs, might be why, and you have an odd error.

6809 NullReferenceException: Object reference not set to an instance of an object

6810 at NavWaypoint.Start () [0x00000] in <filename unknown>:0

6783 [Part]: PartModule indexing mismatch at asasmodule1-2, index 0.

6784 Node 'ModuleSAS' found in loaded data, but 'ModuleReactionWheel' is defined in prefab.

6785 Looking for ModuleSAS in other indices...

6779 PartModule is null.

Maybe the scenario is broken but no one noticed till now, I'll have to try it.

I'm also getting some mass lagging during this tutorial, it's not unplayable, but it surely drops to something between 15 and 20 FPS. My timer at the top of the screen also seems to turn yellow/red then, I don't think this is happening due to my graphics settings because normally it doesn't lag like that. If you find a fix please tell me , I'll be up with the thread.
