Added fuel station tier II (with increased capacity refueling speed).
Fixed fuel stations refueling logic that was not working in some cases.
Fuel trucks no longer try to refuel their station with fuel. Notification is shown when no fuel pipe is connected.
Refueling truck always refuels itself and its cargo when parked at the station. This means that the truck is always ready to go when it is needed.
When a truck delivers fuel to an excavator it also gives any leftovers to nearby excavators. This makes T2 trucks super efficient at refueling.
Improved how fueling stations are chosen. We used to always force the closest fuel station for refueling. Now we just prioritize the closest one but if it is too busy, another one is chosen.
Changed tree harvesting. Only selected trees are being harvested now. This can alleviate issues where a tree harvester was attempting to navigate to blocked trees and was seemingly stuck.
Fixed issues with vehicle spawning where vehicles may not get spawned in some situations. Non-spawned vehicles should be fixed after load.
Improved terrain rendering to not cause lags when there are many terrain updates (many operational mines, etc).
