Stuck newbie with updating a module with Mask


I am trying to update an existing module (Les Maréchaux), because the hidden units can be flipped by all players. I am in the middle of a game and want to continue it.

I went into the module and added a “Mask” trait to all units (as Prototype have no effect on units on the map), allowing only the owner to mask it and setting the display at “Plain”.

Then I went to the procedure to update saved game.

The bad behavior does not change. I must have done something wrong, but I do not have a clue about what it is. It is the first time I explore the module editor.

Best regards,


Hi Guillaume
If you send me the module after your change + some screenshots I might help you. I tested the mask trait in the module I work on.
send to

Ignore the saved game for now. Test the module with a new game.

Thanks ! I believe I have solved it. It was conflicting with the “Layer” properties.

I am having no success updating the old scenario, but I will keep trying !
