Yay, bugs!
- war declaration animations are like that for now, we gave priority to the NSFW ones
- fixed, wait for next patch
- I guess it could happen, you have the "Panic Button" in your inventory to leave stuck battles (who was sieged in your case?)
- yes, a lot of stuff happens in the world map, the northern one is the heaviest one. It depends on your CPU for the most part, but there's always room for optimizations
- Everything you need can be found in the northern map (the wheat is by Harvest Princess reign, if that's the one you couldn't find)
