Resource nodes removed on Hill And Dale Map

I play on the hill and dale map a lot, 2vs2 map size and before that enchanted grove update came along there was pretty much always 3 gold mines and 2 stone mines on each player’s side of the hill (3 gold and 2 stone for me and the same amount for the guy I was teamed with on the same hill as me). Now after that enchanted grove update there’s only 1 gold mine and 1 stone mine per player’s side of the hill, why did they remove these resources as it didn’t say anything about that in the update notes.
