hello,
for donation issues we got a seperated forum, you can post there and be sure that noone else than the devs see your bills (which you need to post for more info) etc: https://pokemonrevolution.net/forum/viewforum.php?f=71
The npc's have fixed moves, they could have earthquake even tho they don't learn it. You'll have to wait until the moveset of gardevoir is updated to learn it
I can suggest using psychic instead of hex for gengar, it helps alot.
Edit: Gyarados also has a moveset that doens't really fit to a physical attacker, instead of icebeam use ice fang and instead of surf aqua tail (that one is optional), only crunch is affected by the dragon dance buff
