Expected behavior

The use of $root/Installer/GOG/$game and $root/Installer/HumbleBundle/$game for storing the installers should store each game in an own folder.

Actual behavior

Using $root/Installer/GOG/$game and $root/Installer/HumbleBundle/$game for storing the installers does not create game folders for each game but creates a subfolder named '$game'. It seems like '$game' is not recognized as a variable by GameHub

Steps to reproduce

Set $root/Installer/GOG/$game and $root/Installer/HumbleBundle/$game as folders for storing the installers in the GameHub settings. After downloading a game via GameHub check the created folder name.
