During a Triple Trouble raid, I received a message saying the map will close approximately 45 minutes before the boss spawned. The guild leaders who organized the map decided to use that map and an hour after I received the message, the map was closed even though it was at hard capped.
This is an obvious bug in which the use case of a map being flooded with people again was not considered. Furthermore, the players who joined the map were not made aware that the map was being closed and were not given the option to leave.
