Point three I agree with, would be great have a faster way to pick a unit in jeopardy then try to work out where it is in the scrum and manual pick it or tell all units of that type to retreat.
I donít think you need a message about the max population for housing. Mainly because I donít like an assumption I want to max/min everything, houses are cheap. I kinda wish I could build more houses then it lets us tbh.
The rate of resource gathering definitely drops when your offline, that was part of a patch I remember quite a while ago. The other fluctuations I've assumed are due to weather and stuff. The rates largely become irrelevant once you hit max built. Which if youíre a regular player does not take very long at all.
