I played through Timberline Falls for the first time last night. The area seems to lack the polish that the rest of game has (from my experience) received. The depth blur bug has already been reported, but I also encountered the following issues:
a. The heart quest in the Rankor Ruins was….incomplete? The description in the upper right of the screen mentioned being able to repair golems, but there were no golems around to interact with. The only way to complete the heart was to find “artifacts” (typically weapons) laying on the ground and put them into storage crates. The respawn time on these artifacts was absurdly low, leading to a lot of frustrating running around. Finishing that heart for the zone completion reward was a VERY tedious grind, so I’m hoping it gets fixed soon!
There was also a dynamic event at the Rankor Ruins which appeared to be “stuck,” which may have impacted the above issue. It involved defending an asura researcher from waves of undead, but the event was stuck at 3/4 waves defeated, with no additional undead around to fight. It stayed “stuck” for the entire 2+ hours I was in the zone.c. The norn moot heart (top left corner of the zone) also seemed to be partly bugged. Picking up buckets of water and throwing them on passed-out NPC’s did not advance the heart, nor did it “wake up” the NPC’s, despite the heart description stating that this was one of the tasks for the heart quest. To be fair, I’ve noticed inconsistent results in similar quests in other parts of the world, where throwing water on sleeping NPC’s sometimes does nothing to wake them up or advance the task, so it may be a more widespread issue, but this one was consistently not working.
Hope all this info helps!
