All I'm saying is, Mae it so natural resources spawn randomly on empty tiles throughout the world when they are ready.. so no one can just horde palisades around them and make bots to harvest every 5 days.
Either that or don't display when the resource will be ready. Make it a random day after its been collected once. Not log in a bot and harveSt in exactly 36 hours.. make or so a number between 50 hours and 100 hours is choosen at random for that item to respawn..
Just an idea, first idea would help with pali blocking all over and second would just mean you might get a chance to get the resource before a bot because it's more unpredictable.
