I'll just tell you, it was Hjalmar.

Avoiding spoilers, one of the major quests has you approach and help someone fight some monsters. In that same place there is a skeleton with a key in it for a different side quest.
After you finish fighting the monsters, a dialog cutscene triggers with the person you just helped, but there is a small window of time between the combat ending and the dialog cutscene starting when you actually loot.
Initially I too felt like I was missing out on content, but the more time I spent away from Reddit the easier it feels to stay away.
I have accepted that I will not get certain kinds of content and communities, but that's a sacrifice I'm willing to make for Kbin / Lemmy. And I believe that slowly, eventually we'll have the quality of the communities we had on Reddit. It just takes time.
It actually isn't fixed because this happened to me only a couple of weeks ago (with the next gen upgrade). But it must be an incredibly rare bug because I've done the "loot before cutscene trigger" a bunch of times before but only once did it glitch.
