Thanks for answering.
I connect this morning (its's morning for me, yes !) and Door's Came back without doing anything.
I think my new update for fortress is the key, but now it's good.
Just an question more, Each time I gone on a map battle or region, I've to re-uprade each unity, these action take a long time and during this time we can't fight !?
Have you others players concerned ? It's Normal ?
Thks for all and dear developpers thx for this good game !
