I've been having an issue where i cannot mega evolve my xmas houndoom mount with pve coins even though it is an option. Every time I click it nothing happens. Maybe it's a bug with npc dialog or something. Been trying for some time now in hopes it has gotten resolved but it's still an issue.
I know that I can buy it with 400k pokedollars, but would rather do pve coins. It even has an option for 100 pvp coins.
Please help. Thanks.
