Load a map and execute flashScriptHashes either through the console or from the options and see if the scripts for that map appear on the list. If they appear, then they’re loaded.
Otherwise, press Win+R, write this: %localappdata%\Plutonium\storage\t6\scripts\zm or insert \raw after t6 if you decided to use that directory instead, press Ok, open one of the map folders, right-click one of the scripts, select “Copy as path”, paste the path somewhere, and check that there are no spaces in any of the folder names. If you’re getting an error from the Run window that the directory doesn’t exist or you’re not seeing the folders you created, then you’re not placing the folders in the correct directory.
