It's most likely because I play the game locally, not interested in ranked play. Seems maybe those logs are only created for games played through the FAF launcher?
If you are simply trying to play alone, you can do that while still using the FAF launcher (create lobby with password so nobody else can join). Unless the fact that your replay will get uploaded is a problem (btw the replay is very usefull to show problems you encountered in the game to others), i recommend playing that way. You will not be able to save, but seems like saving is broken anyway right now.
