Ok got it.
I just make some tests and it works with ai plans indeed.
Too bad objectives are not regarded as ai plans (with standard behavior) if no specific ai plan exists.
It means my project is unrealistic with CMx2.
Just in case, even if it's off topic, do you know if CMBO has a mod which allows use of static maps in QB ? I would like to make my operational game for Market Garden but i need static maps.
Thank you very much for your help.
