The event is only going to be 24 hours, from effectively 1am est sunday-1am est monday or 10p sat-10p sun. if one wakes up at 8 and goes to bed at 1 am, hopefully they dont have to work early the next day, that gives 17 hours to run sr, at 4 energy an hour plus 8 to start,that makes 76 energy. 25 per level, that is only 3 levels that can be made it through. even if you wake up at 5, thats still only an extra 12 energy, which still leaves you short. im sure you dont plan on extending the event length, so is it possible that you move up the milestones so that those that cant stay up 24 hours can complete the milestones to get the museum achievements? i know this is too much to ask and will fall on deaf ears, but you dont know unless you ask.
and to clarify, i dont mean up in the sense of moving them to having to complete legendary to achieve them. i mean make them achievable after the first couple levels.
