No it is not just for you. In the announcement you can find a couple of things that don't work yet in Project Penelope. This is one of them.
Oh sorry , I didn't saw this post.
I have found another bug with the celts villagers and which isn't in the announcement. When I save a game and I load it again , the villagers working in the farms are just standing in their farm , doing nothing.
Maybe it's only for me , but the gold mine doesn't work with the celts. I can't send villagers to work in it. The mine is fuctioning like a tower or a town center. The villagers are automatically in garrison :/ . This isn't an annoying bug but it still a bug ^^
By the way , thank you , all the community of Project Penelope. You're doing amazing work. I enjoyed so much playing Aoeo again since 2 years.
Keep it up !
