In my current game (1.2.5, Mac, Steam), I found a Fragmented Essence of Harkor'Zun on standard Daikara 1 in the middle of a huge pack of enemies right at the beginning of the level (
see screenshot). I've never encountered it before, but from the forums I gather that several spawn together, then the last one you kill becomes a boss. However, I cleared the level without finding any other Fragmented Essences. I know the can do some weird pathing because of rockwalk. Fortunately, I'm playing a Wyrmic, so digging out an entire level is pretty easy. Unfortunately, I pretty much dug out the whole level without finding any other essences (
see screenshot).
The latest posts I found on the subject were from 2013, and nobody actually dug out the whole level. I'm wondering if this is an actual bug, or if maybe now the essences can spawn in different zones. If not I'll just put this in the bug section.
As an aside, is there any way that I could try to go for the unlock? I haven't gotten Stone yet, and I'd very much like to. Plus I've lost two nearly-identical Wyrmics to Urkis (never gotten anyone past him), so having just cleared Daikara my window for figuring this out is probably pretty limited.
