Having it log all dungeons will create a lot of stuff you won’t care about, unless you only run M+ I guess.
To get a full log for M+ you need to start it before the key is entered, if I forget until afterwards it misses the CHALLENGE_MODE_START line. I should really test if that happens when they key is activated or the countdown finishes.
If it’s the latter it might be possible to enable logging before the countdown reaches zero, thus capturing the whole log of just M+ runs.
If someone beats me to testing when that fires that would be great, I need to be asleep already.
