Is it possible to miss the time window through no fault of one's own for entering the Stone Circle on Darknight or have I done something stupid here? I have an ultra attempt in progress, fed and then 'C'hatted to the ratling, did the Gaab'Baay quests and got the Medal of Chaos, and arrived at the Stone Circle on day 58. Proceeded to stand on the Stone Circle map square and press '>' continuously until day 62, with no result other than "Where do you want to go?". What did I do wrong?
