After UCS Savant has been released, there has been a couple of Bugs that occurs in PvP time to time.
1.When i join someone that is about same level or in the range of my level I am in PvP, it Wont! even if its not full!!
It's going to say "Join Failed. Character Does Not Meet Zone Level Requirements."
2.After a game has ended and pressed "Replay" all of these PvP'ers will be separated or be splited into groups or individualy.
3.Low Level Access. Sometimes, Low Level Toon's joining a game created by a L40, Or A high Leveled toon Joining a PvP game Hosted by A Twinker.
4.When you leave the Map, you will not be able to rejoin again, using the same toon, or other alts in that account.
I really do think it's a bug because even so it has enough room for someone, it will say something like "the game is not allowing access"
(Be informed that this will also likely Happen to PvE maps, Including Savant and Hive)
So far, some of has been fixed and came back "again".. I am not sure if These are the only bugs occurring in PvP..
These are just some of the Bugs I myself have encountered. If you have any more bugs to report, post away!
EDIT: added #4.
