Thanks for the in-depth feedback. I was aware of some of those bugs but didn't have time to fix them. I think I'll make a 'final' version of the game with all those issues ironed out. The last bug has been reported by someone else too but I was sure I fixed it, I need to look into it again.
As for the second oversight, I guess the description wasn't very clear but you need to have a certain amount of villagers AND to have a certain amount of in-game days spent managing the town. I'll fix the text to make it more easy to understand.
Thanks again for playing and for the feedback.
