The vignette range extender has a new option to show "mystery" vignettes that exist but are hidden from the API. I can't tell what any specific one is, but they tend to be lootable things like relic caches in Korthia.
Observer Yorik has a new questid, and so won't keep on looking incomplete
Reliwik has an associated vignetteid that'll help with alerts
Mobs that had a mount/pet and toys and regular items as loot had a tooltip glitch with overlapping loot tooltips
