Thanks so much for playing, and I'm really glad you're enjoying the Farfields update! It took quite a while to design these new biomes. I wanted them to feel more challenging than the earlier ones but not overly difficult. There's definitely more balancing to come as I gather feedback since I'm aiming for a sweet spot that works for both casual players and those looking for a harder challenge.
As for wool, sheep regrow it every 500 cells dug in any direction. Cow spawns on the other hand happen every 100 cells dug downward.
Also, thanks for pointing out the anthracite icon issue in the stats menu, I'll come up with a quick fix.
Really appreciate all the detailed feedback, have fun!
Edit: Fixed the bug where Farfields resources are not showing properly on the Current Run Stats menu.
