Sigrdrifa is also feverishly updating EQ2 Wikia’s Tinkerfest guide for 2013.
SOE decides to throw Tinkerfest during SOE LIVE? It would be nice if they held the event the week after SOE LIVE.
EQ2 on Facebook is showing that Tinkerfest will run through 8/13/2013. EQ2i is showing 8/8/2013. I am guessing that SOE is going to run it through the 13th of August.
Yes indeedy. That was announced quite a while ago; we updated to the correct dates on ZAM nearly a month ago. Kaitheel extended it to give some extra leeway to us folks going to SOE Live.
Sorry for the headline malfunction. I got that date from Wikia. I think Zam got all the ducks in a row on their Tinkerfest article around the first week of July.
