In fairness to the developers and @olliepurkiss these changes were needed on many levels. The “timing” part of it is something that can be adjusted and balanced if they made them too long.
Do consider that in the real world when we make changes it takes nature some time to revert. So huge changes in this game resulting in a bit slower replacement makes sense. Personally for those strip mining or things like that, I am happy to see that it might take longer for things to come back…
Also, with the amount of planets that are out there and the resources present on those planets it isn’t too much of a convenience to farm over various locations. This game is about moving around and not stepping out of your door 1 step to get everything you need.
