try going back a step and repeating what you said to the last npc, this might trigger it off from there again.
I'm still wary about doing any quests during this .19 upgrade...and believe it would be wiser to wait until the server is a bit more reliable/stable before resuming any important quests.
Im not sure what your mates in europe are saying, but everyone i know are experiencing the same constant crashes of the server, Im in Oz too.
@Aiken: Strange mate, Im in Australia, and if i cant get on, no one is on, but then my traceroute appears to be different to you as well. I have 15 hops in my traceroute, always with a very good ping though, 148ms, well, when server is up, hehe.
