There are no sandworms on Eco yet. But who knows, it's modable...
As for deforestation, each plant has various parameters attached to where it can grow. Change these parameters by ruining the world around you you could create circumstances were it's possible.
A much easier way to prevent/limit self-reforestation is to only use the logs and leave the site full of pulp and a stump.
check to make sure you are actually getting the quantity you requested. Lots of people are having this issue I've noticed, but it is in beta. We have been cancelling the jobs to clear the jobs. we find that we get the order done, but due to rounding issues it has 1 raw resource left over and when you cancel the job you get that 1 back.
one trick is to do the floor in the required blocks and covering them with rugs. admittedly it would be nice if they added paints to the game. Also there is a section for idea. I recommend posting this topic in there.
there is also a setting that gives you skill points based on crafting. If that is on you can log in put in a crafting order that takes 24 hours, come back and have tons of skill points. Although we have experience bugs where sometimes the crafting job finishes without completely so the job is done, but you have to cancel to clear it and don't get skill points.
Susuwatari, thanks also for this detailed answer.
I am finally going today with a Developer pack (4 pack + access to source code and ability to submit games changes) as one of my sons (and me) are IT people.
Wish you all good playing time.
