No, when that happens it says 'the pokemon has already been traded- I get that message a lot. Iwas only commenting on it because it would not let me do the trade- it said my pokemon could not be traded.
I've traded Pokemon on the GTS and I haven't downloaded the patch yet, but I've never gotten that message. Was it in your party with an HM? I'm not sure what the error message for that is...Did you ever apply the XY patch found in the e-shop? It fixed a lot of issues with the GTS.
Each horde encounter is 5 Pokemon, so the chances of finding a shiny are 5x higher, though I don't know if there's anything else beyond that.anyone done any research on sweet scent? i keep seeing a lot of shiny yanma on the GTS and had friends find shines in swarms quite quick using this method.
am i missing something because i find lots of normal stuff.
