I belong to 5 guilds, however when I open the Guild tab and click on the drop down box only 4 show. The fifth one is not shown. I am still a member of this guild, I can chat, assess the guild bank to make deposits and sell on our Guild Trader. I can not access the guild hall unless I ask for fellow member to go there and I can travel to them. Which is a major inconvenience to myself and my guildmates I feel, no one has complained and are more than happy to help me.
I sent in a bug report, the response was they will send it on to the right people. But it is still not fixed.
I can send screenshots via private message to the GM if they request them.
I must mention this is an issue on my main account I play on.
