With that latest update you revamped the capital.
People were all hyped because even at lvl 40 it was a decent spot to farm coin.
Now you turned that into another "raider island spot" i.e. another useless waste of terrain where no one goes but magistrate of that county to claim taxes.
Suggestion: **Remove that crossbows from there, keep NPCs lvl 60. Level the area back to 40 if you cant decide what to do but wanna keep the crossbows. At least, if you can't really decide; revert the change! **Because people actually farmed there back before the update now its dead bytes server must load.
