Just a heads up, i have been playing the HD upgrade recently, rekindled my interest in the game again, absolutly stunning now. Anyway to get to the point, there are a few minor discrepancies with edge detection, several steps that used to be walkable now require a jump to clear, Ronins gaff being the most annoying. On a side note, i do hope your not going with the Epic fail. 
What platform are you playing on?
PC mate.
OK Moved you to the right section. If you want to file a formal bug report, you’ll need to open a support ticket.
Cheers!
Thank you sir
