Very often when closing Arma3 and exiting back to the Launcher, Arma3 does not shut down and remains memory resident. It appears that this issue occurs more frequently when mods are being used (not specific to any one mod) and when the user Alt tabs back to the desktop or Steam - whilst either in game or in the Editor.

Obviously task manager -> End process fixes the issue but this important / frustrating issue needs investigating imo.

I have attached an image of the exit code when terminating process via Task manager. This will probably be of little use. {F26283}
