Okay, I understand the need to roll out game updates.
But the last hour of an event is NOT the time to do it. Depending on how long the update process keeps the game unavailable, it may cost me event completion, that I was on track to achieve. I bought multiple energy refills--part of that's on me, because I didn't have time on some days to play out all my free energy. I was about to spend a donut on the Washing Machine (I'm glad I was saving that for last).
All for naught.
I am more than a little bit upset over this. The more I think about it, I'm going to open a Support Ticket about it, as well--not that I expect any satisfaction beyond knowing for sure that the devs know that they screwed up BIG TIME on this one.
