We noticed that after installing the new 1.2.2 update a select number of users receive an error message at startup about “Duplicate UniqueIDs foundâ€. This might be the case for you if you have downloaded the tutorial mission before installing this update.
There is a simple fix for this problem. Just perform the following steps:
1) Go to c:\Users\<your name>\Documents\ShipSimExtremes Userdata\Missions\ (or via Start->Documents-> ShipSimExtremes Userdata\Missions\)
2) Select Tutorial mission 1 (filename may be different depending on your in-game language setting)
3) Delete this file
4) Restart Ship Simulator Extremes
This solves the issue.
