Happy hour bug?

[Longlivetheking]

Can u explain for me how the happy hour works?

I see, that money after every battle is doubled, but I dont see that in a normal player vs pokemon battle. Is a battle right? Because we get info that we won a battle but... I mainly farm in cerulean. I dont see more money. In fact I see more money without using this move in a battle. I get like max 600 pokedollars with using it and like almost 700 without using it. Do I need to use this move in a every battle? Or it works only with npc battles? Or it simply does not work at all? And why it was available to get in easter event when its doesnt work at all. Tell me if I do something wrong. Cheers
