Yes, I have noticed the lag too . Some things I have noticed that slow it down: When the AI moves it sometimes seems to walk on top of a cliff rather than walking around it - which cannot be done so takes a long time to calculate the path. (I cannot find a way of specifying tiles as non-passable)When there are a lot of workers gathering wood it seems to lag quite a bit - maybe it is slow figuring out where they can chop. I will have a look into improving the hills to make them more natural. Hi quantumstate, I wanted the map to be more like the Black Forest maps but I was getting issues when I created maps which are covered in many trees (Slow to generate and some JavaScript errors about running out of memory). I am thinking of re-naming the map until I can get something more like the originals. Any name suggestions are welcome
