Need help identifying mod by log message

[OrbitalManeuvers]

Hello, I am hoping someone can help identify which mod is writing this type of message to my log. Here is an  example:

[LOG 09:14:27.950] [PartSet]: Failed to add Resource 386854434 to Simulation PartSet:231 as corresponding Part Leo-B1G-SM "Matisse" Service Module-1662533314 SimulationResource was not found.

I have a fairly large log file in this install:

(There are very few nullref exceptions in here, for its size)

Sometimes it can take upwards of 5 minutes just to exit KSP.  That's what I'm aiming to improve.

So my plan is just to start with the most often repeated message in the log, and the one above is a representation of the winner. It repeats for many different "resource" numbers per part, and seems to list every part I have, on every flight maybe?  So this is my starting point - and I have no clue which mod writes this. I have grepped through the source of several of these mods, without any luck.

Here are the clues I have. This is the full mod set of the install that creates the above log file:

CustomConfigs just has flags. MechJebUnlocked is empty, and probably voodoo/urban legend. The rest are regular ole mods you all prolly have, too. Oh TriggerTech has KAC and TWP inside.

And here is the  I AM STARTING OVER directory, so it's probably not one of these. This install runs perfectly, exits immediately, and leaves behind a 1MB log file. It's basically the QOL and visuals from above, plus restock.

I need to figure out which mod this is before I can figure out how to appease it. Thanks for any help!
