The event ended when it supposed to end on my end...

That said, there are known issues with events when your local time is different from server time. Generally speaking, you should assume that it ends at the designated time and date based on the earlier of the two.

And you are woefully lacking of a screenshot that includes the

1: proof of lack of event

2: proof of server time, to indicate that it is indeed before the supposed end time.

Event, according to bait, end at 1AM. It is, at time of screenshot, 1PM in your server. Even your initial report, which is 2 hours before the screenshot, is after the end of event time by about 10 hours.
