I'm not sure if this is the correct place to post this, but... With the reboot at about 2:45 PM today, the heads used to designate "next page" and "previous page" are broken. They are displaying as standard Steve heads. quick edit for clarification: the lore on the head is displaying correctly, just not the head itself.
Maybe its turned into a supporter feature? Sorry, sounds crazy and most likely isn't the case. But I also noticed this but only after my gold ran out.
The chicken is well aware of the issue, as it happened to me last week and I sent him a screenshot. I think Aikar is working on something to fix it.
