How to diagnose crashes?

[Solivagant]

Hi all, after years applying mods to Fallout 4, enjoying the excellent work of the community, I've started trying my hand at modding. My first attempt was a failure, use the Power Armor Pip-Boy outside of Power Armor, as it seems it would be simpler to do an animation replacer for the 1st Person arm animation that brings up the Pip-Boy, than to call the correct Pip-Boy.

 

My second attempt is a more modest one: the mod Quick Reflexes has a bug where when you use a stimpak from the favorites menu, while crouched, will crash the game, https://www.nexusmods.com/fallout4/mods/23263?tab=posts&BH=0

 

I've enabled logging in my Fallout4Custom.ini, but so far the only logging I'm able to make work is calling:

Debug.MessageBox("I see this message box")

I recompile the script using the Creation Kit and am able to see that message box when I open a menu.

 

My question is how do I add logging lines in my script so that are written to a file. I know Debug.Trace, but I can't seem to get it to work. It doesn't show up in the Papyrus.0.log files.

 

Thank you!
