Continuing the discussion from Warpath allows you to move past the ledge when fighting the Idol of Loathing:
This issue still exists in version 0.8.1d of the Beta. I have captured a video of the problem here: https://imgur.com/a/qqwdOEY
As you can see in the video at 0:04 (0:24 seconds left in Imgur), the character moves off the ledge while using the Warpath skill. Then, at 0:07 (21 seconds left in Imgur), when stopping to use Warpath, the character gets zoomed back to the ledge.
This can get problematic as it can be seen at 0:14 (14 seconds left in Imgur), because the character gets stuck at one point looping the character’s walking animation, disabling you from doing anything but casting Warpath again to get moving, which one can see at 0:19 (9 seconds left in Imgur).
