Guild creation = cant represent
For the record, I’ve seen this happen also. I thought it was a bug in that the guild leader was not able to represent the guild created. I was able to represent another guild but not my own. When I moved servers, the guild lost all influence but I was able to transfer guild leadership and that person was able to represent the guild.
I had this issue with the guild I created. After navigating through a couple zone barriers it finally cleared (not using waypoint zoning, travel through the shimmering portal)
Map to an area that will put you in overflow and then try to represent. They are still working on guild system and most everything with the guild systems seems to work fine in overflow.
Similar happened to me (could not represent). Character change/logout did not work. It did work after completely closing the game, and loading it again. Then I could represent normally. I could have landed in an overflow at that time, so the changing zones, going into overflow might be the workaround.
