Yesterday it was 1500000 or 1800000. After upgrade new version it went to 2000000. This is ♥♥♥♥ up, you should keep it same price to be fair for new player.
Supercell decrease lvl 6 mortar down from 2.25M to 1.6M, a saving of 650k. Overall you save 1.95M (650k x 3 mortars). So increasing TH 8 by 600k is no big deal. Plus, Supercell increase the loot percentage. All in all, great update with some bugs/flaws.
