My crystal aura disappeared

Hello, today before i went off for few hours i had bought crystal aura for like 40 days… and now the game tells me that i have no crystal aura active… why?

I had the same issue and it took like 30-60min until my Aura reappeared after logging in.

Well, so now i can go afk again and wait until it comes back out of nowhere?

I still dont have it so yeah… nice game
