I've been playing this game since January & the schedule has always been like this - but, as jaimmyc pointed out, it lasted 3 hours instead of just 1 hour.
Last month's schedule change was bad for different reasons &, thankfully, was changed back to the normal schedule.
A suggestion to the GMs:
I don't know if this is possible, but how about having the events twice a day on the specified days? During the event, a player is only allowed to participate in either one time schedule or the other - not both. Like with Dragon City Military Training - once a player has done their 10 rounds, they are no longer allowed to take anymore rounds. Same would go with the events if they were given 2x a day.
I have no clue how much work that would take, so its just a suggestion.
