I'm on the most recent official version of Vintage Story and it seems I can't knap any tools. When I place the flint or any other chippable rock down to form my character can't break the pixels. I've tried pressing Alt and left clicking along with the other suggestions. Recently I uninstalled and reinstalled the game which didn't work as I heard it could be an update issue but that didn't change anything. I uninstalled all my mods out of desperation, but I am still encountering the same problem. If anyone can give me any suggestions on how to fix this issue, I'd be greatly appreciated.
