Book of Skill from Reflections of Terror missing

Bug report number: 2,832,390,316

I was accepting rewards from multiple Hargan quests and somehow the Book of SKill ended up deleted. My quest still says to use the book and talking to Hargan has no option to grab the book. I tried going back and killing Yugul again but nothing changed.

I used the /passives command to double check it wasn't there, as well as the /recheck_achievements command just in case that helped.

Edit: It was in my WW Rucksack - I am dumb.

Check your Wildwood rucksack.

Damn I feel dumb now. Totally forgot I had WW on this toon
