The event in-game timer said the event would end a day later than it did. I went to bed figuring I’d be able to clear it today only to find it removed from the game.
What says this doesn’t happen again in the future but it is a 5 day discrepancy instead of just 1. Maybe even 10. Perhaps next time it happens they allow you to buy parts you missed like in other events. “oops it ended way early, you were so close to the end! Spend more money and buy the rest”. This is not a good precedent.
The majority of players are not going to internalize the time the event ends from the patch notes, if they even read them at all. They will look at the in-game timer.
