I've deployed other minor fixes see below

Caverns of Time
At this point, I would like to draw the attention of all players to the opening of the Hyjal instance and the other instances of the Caverns of Time. I went through it and tested it and it should work well enough, but I ask the players to come together in a sufficient amount and number even as they specify the rules of the server to let me know of any irregularities or errors. All bosses are scripted and Archimonde himself, which is finally executable from the event, the functionality of which you have to study on the Internet, is too extensive to write here. Thank you to everyone and especially to my team for the patience shown in testing this instance. The next one in the order Tempest Keep is closed, so they remain until all TK-The Eye, Zul'Aman, Magisters' Terrace and Sunwell Plateau instances are fully resolved.
