Welp guess I missed it for nothing then! I missed one of the huge world boss events in the living story too due to a similar problem, I was glad they put some reasonably hard content in at least but I wish it didn't rely on 100 other people pulling their weight at the time, lol. For world bosses like Tequatl it's cool but the fact it was limited time just made me miss out on it entirely even though I actually tried a few times to do it!
