Stack Overflow crash

[Krazy1]

Uh, KSC, we have a problem.

In KSP 1.11.2 and 1.12.2, while flying a particular ship (Citadel 3) in solar orbit with a Jool intercept and maneuver nodes ahead, I'm getting a stack overflow, log spam and in 1.12.2 it also crashed to desktop.  I used Planning Node previously for this ship so that's my first suspicion. Only difference between the installs was [x]Science beta from LGG was only on 1.11.2.  Have 38 other mods installed with CKAN.

I'm seeing this on both versions... but again [x] Science wasn't on 1.12.2 so I don't know where this is coming from.  It does this at the start of every scene change, not just flight. Anybody see this in stock?

It continues to spam after this. I noticed on the map view, the orbit patch is rapidly flickering, sometimes intercepting Jool, sometimes not. I've seen this before without any problem though.

I'll pull out Planning Node and see what happens.

UPDATE:

I tried removing Planning Node on 1.12.2 and it initially seemed OK flying Citadel 3 but when I zoomed to Jool and edited a man node, it started spamming the log and CTDT when I pressed ESC.

To be perfectly honest, your best bet in situations like this where your log isn't obviously blaming a candidate is to start doing the binary method.

Remove half your mods (make sure you leave any dependencies) and see if you can reproduce the issue (probably in a new save, as loading an old save with half it's mods installed is asking for trouble). If the issue disappears, you know the problem is in the second half, so replace them and keep doing that into you narrow it down to the minimum set of mods required to reproduce the issue. Then report the issue to the mod makers and provide your logs etc, as you have here.

Well, long story short... 

I loaded a savegame copy in unmodded Steam install (checked file integrity). There are mod parts in other ships but not the one in question. It does show some warnings in the log for entries in the save file with no associated mod, but no new errors/ exceptions. It behaves the same in game.

It still crashes to desktop when I view Jool and set the target to Pol.

This is bad. Even a corrupted save file should not crash like this. It looks like a core KSP problem. The end of the KSP log got cut off but this is all there was. There's no error detail in either file.

KSP log unmodded

Player log unmodded

Update:

In stock KSP and new sandbox game, I tried cheating a ship into sun orbit and set lots of maneuver nodes and targeted Pol and it worked fine. Guess it's the save file somehow. I'm playing career and I've done probably 20 contracts since I launched that ship. I'll see if I can reproduce it with other ships/ planets. I'll probably end up trying to edit my save file 

Update 2: 

I cheated a Mk1 capsule to set orbit/ rendezvous with the original ship (Citadel 3). The capsule still produces the same crash: focus on Jool and target any Jool moon... game over.  It does this unmodded or modded. This is very bad. If it's something in the save file, it's not the ship.

I have to figure out how to set the orbit and time exactly the same in a new save. It still could be the core game.

I just noticed in the KSP 1.11.2 abridged log I missed the very first exception on line 11770:

Yeah... if it's referencing the center-of-lift marker after it exits the Editor, it will have an NRE. 

Also in the 1.12.2 modded KSP log it has this at line 13220:

This time I apparently used QuickGoTo to jump from flight to editor.

Update 8/24:

In unmodded install, I deleted the original ship (Citadel 3) in the tracking station and flew the test capsule that was previously cheated to the same orbit at that ship... and it still crashed when I targeted a Jool moon.

OMG! I got it... pure stock crash to desktop.   

Moving to unmodded forum.
