I'm on level 84 forest. If restart level 1 and I complete it, what happens? Will I move to level 2 but keep all of my levels? Will I restart level 1 again? Will I jump to level 84 restarted?

You will move onto level 2 but keep all your levels still so once you exit explore you can continue level 84.

It will only reset the level you are playing on, so you will keep all your levels. Anytime I train new wolves, I always train them at Level 5 forest over and over, and I've always kept all my levels.

Okay, thank you so much!
