We are aware of the issue, unfortunately it's not consistent. Any further info would be helpful, such as specific character names and handles, the number of times you've switched fleets, if the character was online when the invite was made, or privacy settings. Any info of this type would be helpful in tracking down the problem.
My characters name is Zander@fltadmiralzander. I have switched fleets with this character maybe 4 times total. This character has been both online and off line when invites were sent out. I have had fleet mates try to invite this character and I have tried inviting myself several times. All of my privacy setting are open so nothing is set to block any type of invite for anything.
i keft a fleet to get to another one but it wouldnt i recieved invites from hundreds of people and nothing worked i even created a fleet with 4 people and it created teh fleet but without me i also check with the gm they said its a fault on my end of the game and to restart the game and internet connection so basicaly im fleetless until this crap gets fixed
I'm having the same issue, and it's been solidly that way for about a week and a bit. Character is Jerry Dougal
Started in Starfleet Dental, left fleet to join Shutup Wesley, rejoined Dental, left again to do some business. When I tried to rejoin, the invite came through, I accepted, but there was no effect. Attempts today to get me back into the fleet have given the message that I already have a fleet invite. I submitted a ticket the other day, but haven't got a response.
Update: A subsequent attempt worked and I'm back in the Fleet. It sounds like a similar problem to how the Bios don't load a lot of the time.
