I noticed that some settings do not get saved when exporting, which I assume has its reasons for. like hide world in traveler and allow travelers in traveler as well. Noticed some of this with other mods as well. Just wanted to know if there was a list somewhere with all the settings that aren't saved using the export function in overwatch so that one can either plan for it or find other work arounds.

Sadly no, there is not a list, but we can start one here, I know of

these are always false, do not save
Overwatch > settings > Testingcheatsenabled
Retuner > Show Object Menu

C-Dark, From my experience:

Allow travelers (traveler mod)

hide worlds (traveler mod)

relative motives (relativity, not a 100% on this one but I’m pretty sure it didn’t save for me).

ive noticed that it generally affects those settings where you can press multiple at ones to either them true or false at once. Basically where instead of clicking and automatically switching, you first mark them and switch them all between true and false at the same. Maybe just a coincidence but thats what I’ve noticed.

Also Mastercontroller CAS settings do not save.

I hope I don't just put a meaning into random outcomes, but it looked to me that the chance of settings getting carried over is higher if I don't use the "all" setting on export but leave menu points I didn't change from default out.
