Issue Description: since some time (can't recall whether due to the current or previous versions), when handling a mortar shell the "Change number of charge rings" is ineffective.

More in detail:

• the inspection action is successful
• the action "Change number of charge rings" appears and the 'F' key press is suggested (default key)
• when pressing 'F' the little triangle moves down, indicating that the key press is detected
• though nothing happens the number of rings remain unchanged

I tried to uninstall/reinstall multiple times, the issue remains. I also removed the $USER\My Games\ArmaReforger files to make sure there is no influence between multiple installations.
