- Implement AI land marks which only used to tracks visited areas on the map for now. Significantly reduces wasting of cpu time by AI checking same place several times (10x or even more in rare cases) - More branching in walk algorythm which allows for better coverage of reachable places. Sometimes makes AI perform ridiculous jumping just to make a tiny step. - Small fixes/adjustments
