Sometime in the past the original R15 idle pose was replaced with the Rthro idle position.
Original pose (From an old picture i saved years ago)
Current default pose
Expected behavior
Since the Rthro pose is already part of an animation bundle, some people may prefer the original look and pose that they can no longer obtain on the website due to it not being in any animation package.
Same goes for the running animation, the original R15 one used to be one of my goto, but now it defaults to the Rthro one. I’m sure it also happens with other types of animations even if I personally never noticed.
