Those changes have not yet gone Live, as noted in the patch notes. On another note, we're currently working on the bug where Join Combat will sometimes fail to send players to a combat area when the timer hits zero. That should be in the next update, alongside fixes to the spawn system, beacons, and not the Dalton.
Can you also fix Join Combat trying to send you to an entirely different continent when the one you're on has several perfectly good fights? It's particularly annoying when you had to go through a long queue to get in, since not paying attention can result in you leaving in the middle of an alert with no way of coming back quickly.
That's something we're currently investigating as well.
