Yep, as of 23rd October, this bug is still present.
I’ve only found it turning up in NM onwards (so far), and it seems mostly connected with ‘underground’ style map areas causing it to activate, and ‘open air’ ones where it wears off. But I don’t play Amazons very often, so my experience of where the skill could potentially go wrong is limited.
This makes playing an Archer on HC very precarious…
