I got it from time to time, but today, during the last hour, it became extremely abundant. First it was in Luna instance, I thought it's about Gold Sand traders (but what did I click to cause it?), them it didn't react when I actually clicked on Gold sand Traders shop in Luna, then it began to repeat on in every Aion client that was in an inactive window, every time I switched to it. Then in active windows too and everywhere... Spreads like a virus, I don't know on what it depends, what shop do they mean, surely I will close Aion after I finish playing these characters and maybe even repair files. It wasn't so bad before.
