Hey there,
Dunno if this is intentional or an error, but i noticed i get absurd amounts of xp from trees when i upgrade mining speed. i have level over 50 and can chop down about 20-30 trees and have a levelup. coincidentally i get huge amounts of xp from science - 3-5 levels. is this also intentional? I should also mention, that i have not played around with any settings
