When run in vscode and fmtk, there are 10k lines of warnings about prototype fields that don't exist. I will look into it, but suspect it's out of my control.

When run normally, the log file is a sensible length.

Looking into it more:

Many of the prototypes in question aren't even touched by my mods, or Icon Badges.

First line of current.log :

0.001 Program arguments: "c:\Users\sandy\Desktop\modding\bin\x64\factorio.exe" "--mod-directory" "c:/Users/sandy/Desktop/modding/mods/" "--instrument-mod" "debugadapter" "--enable-unsafe-lua-debug-api" "--check-unused-prototype-data"

I'll just turn that off and move on. Nothing to see here. I just won't be able to check for any of my own unused prototype data.
