Unable to Load GuardOutput.tmTheme

Whenever I install or remove this package from ST3, I get the following error in a pop-up alert:

Error loading colour scheme Packages/Guard/GuardOutput.tmTheme: Unable to open Packages/Guard/GuardOutput.tmTheme

Just stumbled across the same Issue. Here's my solution:
If you look closely you can see that the path to the theme is hardcoded to Packages/Guard/GuardOutput.tmTheme

Make sure the name of the folder under Packages/ is Guard, either by installing (copying the extracted github-zip to the Packages-Folder) manually or fixing the path after installing via package manager

Yes, since I am using Package Manger, the plugin is in Installed Packages, not Packages.
