Hi,
I've come accross a "funny" bug. When you rename (at start) the scenario folder, you just should never use "r" in the name
Like: Instead of 1805Campaign, don't try 1805CampaignFr . I don't know why, but as soon as I typed Fr at the end, the game started charging, without asking me what side I wanted to choose. After the scenario has finished charging, the game asks you what side you want, and once picked, there is a critical error. (happened twice for me).
I suppose it has something to do with the "r" meaning rename or reload leure:
