Lag, Constant Disconnect, Error 90000, Unable to Log In!!!

Dear SE and moderators :
Ive read alot into this an everyone that I read or talk to about this issue are having similar or slightly different experience with this problem
This is in regards to a bug that apparently is happening to many people in all servers
Bug: Entering a instances then being kicked before it starts and then unable to log back in because game doesnt log out your character from instance-error 90000
This is not a problem with connection this is a bug.. for me it started after Jan 21 hotfixes but others started after big patch, I have never had any problems with this game before Jan 21. I see the minion animation bug has been fixed and ty.. but to pay for a service that cannot be played.. sure I can log in do fates, craft, chat, but as soon as I try to enter any instances the dreaded 90000 error.. now I know at least 3 people who have left game for this reason and seen prolly 50 people on my server have the same issue.. I have proof in the form of other players this bug kicks you then keeps you logged into game so you cannot log back in for hours sometimes days. Julius Maximus and Blood Star, Dylan Weaver, Rikku Moon, my whole fc and many others I could list have seen this bug affect me and others. I have played this game with no problems from the beginning this all seemed to start around Jan 21 for me anyways. I have also read in the forums many others stating this problem so I would hope you intend to rectify this problem. I have lost close to 2 weeks of game play, my static coil groups as well as beast tribe points, myth drops, etc that I will never be able to gain back.. its very disheartening to fall behind in game play when im a very active playing spending at least 5 hours a day on this game. I have had to play other MMO'S and games due to this 90000 error and am asking myself whether I should cancel my subscription with SE because to pay for a service that cannot be used seems wrong. I know this is a issue as I have read about it in hotfix problems and forums , Ive even had a moderator say it has already been brought to your attention, but fact is many people are having this problem and even leaving the game.. which I do not want too do as I love the game and have puts so much time into it its not even funny, but I cant play. I had 2 days free of this bug and thought wow its fixed but sigh it is not... please instead of updating and adding content focus on things like these errors people are having, dedicated players who are being turned off game. Like I said I love this game, it an amazing game that ive had no problem with since launch until recent, but there is a limit of errors to how much anyone can tolerate. Thank you
