Launching Arma 3(v1.55.1333.46) plain vanilla from Arma 3 Sync with no addons. Eden editor. Zeus game Master logic placed. Objects are not placed using Zeus. Using a working mission file.

Editing scripts other than sqm file in text editor and esc+alt/tab between editing using text editors seems to be removing the assets/objects from the existing mission.sqm file. When mission is reloaded nothing shows but the satellite map view from startup. In viewing the sqm nothing existing but the intel data. If player is added again...no assets exist. Did not realize at first but after 3rd or 4th occurrence I realized that all objects were removed from the mission file.
