Oakwynd: Mysteriously Leaving and Rejoining Group on Zone

I had picked up a cleric in BB after using a zep to get to them and then from BB we ported to Feerrot , just the cleric and I, everyone else was in guk waiting. Once we loaded into Feerrot I realized I had been kicked from the group. I was like man....I got used to port you from BB to Fee and then I got booted ? The cleric said he was booted too. I figured w/e and I went to Rathe mountains and he went to swamps (assumed he had lied and was still in the group) and when we each zoned into the next zone we were both magically back in the group without accepting new invites. We were unable to talk in group in Feerrot also , had to use say.
