[0.15.21] Losing saved login and favorite servers

[EntroperZero]

When I browse public games, I'm asked to enter my username and password again, and after I log in, my favorite servers are not remembered. This doesn't happen every time I exit the game and restart, but it has happened 3 or 4 times today. It just started happening with the 0.15.20 or 0.15.21 update.

Can you post your log file,
Are you using steam cloud syncing?
Do you have any anti-virus or file protection on your factorio user directory?

Hello,

I'm experiencing the same problem. It happened twice in the past but today I had to log in every time I started the game. "Connect to Server" IP has also disappeared.

I'm using Steam build with Steam Cloud and Avast antivirus.

//EDIT: Attaching two new log files.

Sorry for the delay, I was out of town all last week.

I am using Steam cloud sync, and there's no antivirus running. No special permissions or attributes on player-data.json.

I just started the game, clicked browse multiplayer games, and it asked me to login. I did, and then exited the game normally. I've attached my log file for that session.

If you delete the file, then log in within Factorio, does the file get recreated with your Factorio username?

[EntroperZero]

Deleted player-data.json, and it recreated it on exit. Seems to be working normally now, though the contents of player-data.json also seem to be the same as they were before... really weird.

Strictly speaking, the authentication token should have changed.

Can a dev confirm what happens if the game holds an invalidated token in the player-data.json file? Does the game manage to replace it in the file?

This seems to be a mystery.
