Briarthorn Den Heart
Old thread, but bumping back up because it’s still an issue.
Ride the Lightning briefly changes my first five skills to no skills. This drops the Briarthorn Den disguise, and if I am anywhere near the front, I’m kicked out of the area.
At the skill point towards the back, Ride the Lightning rushed me forward, and now my character is in Briarthorn without the Nightmare disguise. So apparently the disguise is dropped due to this skill — hoping that this extra information assists in debugging the issue entirely.
