Full den glitch..?

So, I was in Jamma, the server Aladan, I was wandering around as usual when, someone calls out that he is having a trading party. So, I go there. When I got there, i ended up in Coral Canyons. In a whole different server. I tried again. It happened again! Was this some kind of glitch that meant his den was full? I'm guessing... Oh well! Happy New Year!! :D
