Slitherine

Launching a skirmish on multi, i wonder how is it possible as i get a message from engiine saying we don't have the same scripts and/or data ?

Most likely you and your opponent are not on the same patch of the game. Another possibility is that one of you have a modded script/data in the primary game folders.

Yes, Karvon is correct. It is hopefully just a mismatch of files because one of you had not updated to the latest patch, but if it continues every turn you should post here again, especially if you notice any strange things occurring in your game.

Games worked without any bug, i re install my game and clean cache, now it is good ; i have seen a suspect file concerning "maps" was not deleted in desinstallation (file that i never modifiate in any way)
