Glad you're back. Unfortunately my greeting is attached to a bug report.
Code:
[LOG] Innceth casts Siphon Vigor.

What confuses me is that it doesn't always do this, and I can't figure out any pattern. In one case, I was firing down a corridor but there was only one target; firing at a different angle that still only hit that one target worked. In other situations that didn't change anything, so I don't think it's actually targeting but I don't really know.
I'm at a loss. Hopefully it's not a mod conflict.
When this error pops, nothing happens - the ability doesn't fire, the turn doesn't proceed, etc. Most of the attempts were against a rare mob that was causing me some issues, but this log's actually from a bog standard cave bear (or some other bear).
Further testing: The error can happen even when nothing's in the targeting cone.
