I began this quest ages ago, became stuck at the part where we need to find an item somewhere IC Arboretum, abandoned it and moved on to other things. I've now completed many of the Kragenir side quests and main quest, so am back to Vampire. Once again after an extensive search I've yet to find an item that updates my journal.
To complicate matters, I have a vague memory of coming upon an item at or next to the base of one of those circular stone statue pedestals (or maybe a mini garden). But picking up that item triggered no update. Nor do I recall what it was I found then, or what I did with it. Might have been coincidence?
To further complicate matters, I run ImpeREAL City - Unique Districts, which alters the Arboretum. Prolly doesn't matter, since ImpeREAL alters all the districts to an extent, and has never yet affected a Kragenir quest. Still, it's worth mentioning.
Unless there is a known glitch with this phase of Vampire, I'm looking, as mentioned above, more for hints at this time rather than an out-and-out spoiler.
Thanks in advance!
