There is a new version of the Guild Event Manager (GEM) software that the Honourbound Alliance uses to coordinate shared raid, social, and instance events. The 2.27 release attempts to address the recent lost sends experienced by THB members in both their guild channels and in the shared Honourbound channel, as described in my earlier news posting about New Chat Bug & GEM Problems from October 25th.
The new release attempts to solve the problem by increasing the amount of time GEM must wait between sending messages. Note, these are not the messages you are typing. The mod itself works by sending messages to the Honourbound channel. You don't see these mod messages because your mod filters them out and uses them to update your copy of the GEM events calendar. Due to the way information is shared, it's vitally important that everyone update. People who don't update will still lose information which will result in their copies of the event calendar being wrong and then shared incorrectly with other people, continuing to cause events to disappear or people not to appear signed up, etc.
You can update by downloading a copy from one of the following locations:
