Bugs I've encountered, replicated and been annoyed by (not counting a major one, which I've already reported to the devs):
Gorgons sometimes ignore The Earthmother's Entanglement Boon. I can't see how this would be intentional, so it'll be on here. Only seems to affect Gorgons, for some reason.
When dragging items - recently - they don't actually follow the mouse. This has led to some rather unlucky conversions for me, as I've accidentally 'dropped' the wrong item onto the conversion bar.
Most likely not even a bug, but some game mechanic I've yet to fully comprehend - sometimes, gods don't give free Glyphs upon worshipping. I know that they don't when converting... but apart from that, I can't really pinpoint how it works. I've had cases where they don't give their Glyph even when it doesn't appear naturally in the dungeon, which disproves my theory that they only give it if it doesn't exist, and I've had cases where they do
give their Glyph even if it already exists... how does that work, really?
