This is something that has been bothering me for some time now. I live in EST and the ‘new day’ starts at 5:00am, which is not a problem at all.
The problem is that events start at radical times and often without any or very short notice.
For example, the Mickey celebration event went live at 5:00am yesterday while I was active. I work nights so this often is a small boon for me. However, when I woke up in the afternoon there was an update that added new features including the blimp which doubles Port drops. I had blown through my port attempts already and as a result missed out on millions of dollars that I would have loved for upgrading my characters.
This has happened a number of times – I will use my stamina in the morning before I go to bed and when I wake up I will find out that double drop day activated at like 9:00am.
Please, please either standardize times (all events immediately activate with the new day) or give us 24 - 48 hours notice in game so we can plan around it. No one should have to wait through half the day before playing out of fear of missing a completely random event.
