I'm having fun playing your game. The only issue I've encountered so far is a crash whenever the AI took my castle. ( I'll see if I can reproduce this in case you need it. ) Also, micromanaging unit spawns gets a little tedious after a while. Maybe add rally points that can auto-add them to a garrison or army?
I think I've found the bug relating to claiming towns, and fix will be up sometime today. About micromanaging spawns, that's actually exactly the solution I was planning to do - they spawn with a path to the nearest town, and you can choose to alter that path. I hope I'll also have time to add that today.
Thanks for playing! :)
