I'm on the "Defend the Silenar and the Greenlady" part and can't get the mobs to spawn so that I can kill them and continue down the path. There's a good 20 other people stuck on the same part running around as well. I assume the fact that there are people on the same part spread all over the map is what is causing the bug. Regardless, I'm pretty much unable to get to the next map until this quest is done so please post a solution if there is one.
