Read this thread if you want to hear how you can still do it and see a video about it.

Also, spiders don’t despawn after failing the first attempt, so more will gather and attack in greater swarm when the party reaches the Nightmare Tree again.
The spawning is the same issue the first Gates of Arah event is having. These need to be fixed as well.
Linking threads that supports this issue. As far as I know, this unannounced “change” happened around the June 11-13 update.
