[LINUX] - Achievements do not Unlock

[MimaHakurei]

Likely caused by a malformatted achievement.txt path.

Here is an excerpt from my Player.log:
Could not find file "/run/media/nep/media/SteamLibrary/steamapps/common/Higurashi When They Cry Hou - Ch.7 Minagoroshi/HigurashiEp07_Data/StreamingAssets/Data\achievements.txt". NullReferenceException: Object reference not set to an instance of an object at Assets.Scripts.UI.MainUIController.OnGUI () [0x00000] in <filename unknown>:0
The "...Data\achievements.txt" should be "...Data / achievements.txt".

Seems to be specific to Minagoroshi since I had no problems getting achievements in the previous chapters on Linux (unless this bug was recently introduced).
