About half the time these days, Gateway to Gre'thor Advanced fails to detect that you've finished all the objectives (destroyed the Dreadnought and the rest of the Herald Fleet). Sometimes it takes a few seconds or as long as a minute and finally figures it out, and usually that delay causes the bonus timer objective to be denied. I just had an instance where we waited about 15 minutes. It still didn't end, AND we all got AFK Penalties so we have to wait 30 minutes to join another queue. Please fix!!
