[0.17.4] Failed to load local achievement data when using mods

[Skybreaker]

Bug:
The game when modded does not save achievements. Not only does it one time not load achievements, but the game consistently will launch with this error and start with 0 achievements.
Message "Failed to load local achievement data. Local achievements might be lost." on game start.

Code: Select all

   1.242 Info PlayerData.cpp:69: Local player-data.json unavailable
   1.242 Info PlayerData.cpp:72: Cloud player-data.json available, timestamp 1551698732
   1.243 Error PlayerData.cpp:212: Failed to load achievement data: Map version 0.14.22-0 can't be loaded because it's lower than the minimum input version (0.15.0-0).

Repo:
Enable a mod, any mod that disables achievements.
Copy the attached file 'achievements-modded.dat' (you'll need to unzip the .zip first) to your Factorio config folder (this came from my Factorio config folder. It seems to have last been modified by me 2017-04-19)
Start game and observe bug

I'm guessing you can also repro by last using mods in 0.14 of factorio, then slowly updating.

Fix:
Delete the achievements-modded.dat file from your %APPDATA%\Factorio folder

Notes:
I bet this will be a won't fix, since it has to do with loading old data. But I wanted it to be a tracked bug, and searchable by others. It took me a while to find which file was causing this issue.

Thanks for the report. That is indeed not a bug - the achievements file was created with 0.14 and was never loaded and or changed with any game update. 3 major versions later we dropped support for 0.14.
