Check your local priest of discord, he may have a vote going on till June 12th about this very subject!
Yes we all saw that message too which raises even more questions since the Sense Heading thread, and the announcement on the main page said PoP and LoY were going live at the same time on 5-29. The sense heading thread still reflects that which is why we're trying to get a dev to weigh in. Also there is a vote out for LDoN that conflicts with the Sense Heading thread as well. LDoN and LoY both were not supposed to be votes at all.
This is now fixed and LoY is available. The Poll that came up, though Labeled LDoN was actually for LoY. We changed the controlling scripts to NOT ask for a vote for LoY which, as soon as they were updated, completed the unlock for LoY. This will also fix the issue for Lockjaw when they unlock PoP
