I think a frame of the walking animation is missing. Whenever i walk left or right the character flickers at the end of the animation, does anyone know how to fix this?

Sorry if this is getting to you too late, but I have found a solution! As far as I can tell, this is a bug exclusive to the most recent update. You can revert to a previous version of the game from the game's GOG page.

1. Click "MORE."
2. Select "Settings" from the drop-down menu.
3. Select "Manually" under the "Install Updates" section, and then rollback to "5/17/2016."

If this specific one doesn't work for you, be sure to test it on a new profile or try out different updates.

Hope this works for you too!
