How long do player heads take to update after the player changes their skin? Forgive me if this is the wrong forum for this. I couldn't find out on the wiki.
Well, my experience has been that when I changed my skin I saw the skin update rather quickly but none of my heads changed when I was logged in as me. However, all my heads showed up as changed to all other players immediately. Not sure what's up with that, maybe a caching problem but I haven't looked into it.
It updated to my new skin after the server rebooted. Not sure if that did it or if I just needed to wait a few minutes.
