Just tried to lay a sneak assassination (while using a invisible potion) on the hag of the big bad bog hag while she was in her human form in the Save Mayrina quest but as soon as I dealt the damage, the screen cut to black. The battle music started but while the cursor was still available and audio still playing, there was no way for me to tell what was happening.
Reloaded and successfully pulled it off - but thought best to report it just in case.
