Clear the poisonous urchins from Lashoosh
FWIW, I got that a couple of days ago, not close to a map restart or patch, so it definitely sometimes spawns. Doesn’t directly help you out, but how long did you wait around for it — and did you clear other events in the region? It’s not the most … popular of maps.
It looks like this event is still broken (in that it breaks and won’t start until the map instance is reset). I’ve been waiting for over an hour today and about an hour yesterday (same instance, as Snowden Drift will only generate other instances if there’s a daily event going on there).
One big problem with the mega servers: you cannot switch instances of maps anymore, if all servers of a region won’t be enough to fill a map to generate a new one…
