NaN Bug [0.24.2, Modded] - Repeatable

[KerTrotsky]

Not sure if this information should go in the previous thread I posted. In any case :

Windows 8.1 pro, KSP 32 [0.24.2]

I am able to duplicate instantiation of a NaN application event, on the launch pad.

It appears to be related to a procedural part, specifically a procedural decoupler - when that decoupler is activated, the application goes into the familiar "NaN" mode, from which point one must exit the application.

I have two persistent saves which are identical in every respect except one.

In the first instance 'IWSAF - Main NBT1' a vessel is on the launchpad (Aristarchus I - NBT) with the procedural decoupler as the next stage to be activated. When activated, the application goes into NaN mode.

In the second instance 'IWSAF - Main NBT2' same vessel is on the launchpad, except the procedural decoupler has been replaced with a standard stock decoupler. When activated, the application behaves normally.

Searches of both persistent files for instances of NaN before and after testing was null.

The mod list is posted below. The procedural decoupler is from Procedural Parts :

I will be reporting this bug in the Procedural Parts forum. Will also be uploading the logs and persistent files, not sure how useful they are.

Edit (Bug reported to swamp_ig github location for procedural parts)

Drops :

PP_NaN_Error folder on containing identical saves with 1 exception (described above)

After running the IWSAF - Main NBT1 gamesave, the KSP log file has the following entries related to the separation of the procedural decoupler :

[LOG 12:09:18.225] [proceduralStackDecoupler]: Activated

[LOG 12:09:18.226] [00:00:00]: Liftoff!!

[LOG 12:09:18.271] Look rotation viewing vector is zero

[ERR 12:09:18.280] Invalid parameter because it was infinity or nan.

And this goes on in the log for a while. Something going on here I think.

Ahahaha it's my own (well, swamp's, but implicitly mine for not fixing it yet) fault.

Thanks for this!

I don't understand. What if anything did I find here?

[NathanKell]

I don't know what the bug is, just funny that I was blandly speculating on your prior thread without realizing the problem is in my department. :]
