Read what I said ‘People have been claiming’. I’ve seen you on the forums as much as I am. I’m sure you’ve seen the people claiming about going to T5 and T6 worlds and not able to find any gems, and that the planets are constantly full of caves created by people already mined there.
Then in a few of them people were speculating that the Regen script is broken, regenning rocks instantly but resources like coal, gems, and so on is much slower, and keeps stopping or resetting when people costantly come back, see the rocks respawn and think everything respawns, so redigs the area, find nothing and leave. Rocks respawn isntantly, and resources are slower and repeats.
