Embarrassing question - How do I know which mod is generating a red message?

[ohgodspidersno]

I'm actually a developer IRL, so I know that mod conflicts can be a twisted web and that the 'real' issue may be happening deep within the bowels of the stack trace.

But when I click on a red error message and read through the full stack trace, I cannot for the life of me find the actual mod that was being loaded at the time the Exception was triggered.

This information MUST be in there somewhere, right? Why is it so hard for me to find?

It depends on the message?

If it's a red message generated in vanilla code....sometimes it shows, and sometimes it doesn't?

Because Rimworld interpret mod code as standard code.
Unless there is problem with a special non-vanilla definition/string/patch you might have a chance to assign that error to specify mod.

Thats made it nearly impossible to track down error's at a late gameplay with alot of mods, and when the error is critical that colony is lost.
