I think its do to the daylight savings time change. I'm in the central time zone and every since the daylight savings time change just before the last IB it closed at 3am instead of 4am as it use to. I'm assuming they don't use a time change in the region they are based in, so the reason for some thinking it closed early. I'm assuming the same this time this IB, but I'm ok with everything cause I finished my IB playing at 12am. Edit: just say there tweet stating they did state they would close early. I just thought that cause I though I noticed last time it was closed early right after the daylight savings time change.
