What happened to the announcement!??

I'm with Dreamsfear on this one - I plan my buf patterns to match my daily routine. So I do baskets in early am, (or as early as possible on Thursdays), sandwiches in the afternoon & baskets again at night. Stopping "time" during maintnenace would be a bad idea and you'd lose out on all the production.

They cna message to buy gems in the game, why not warn about this?

I don't see the big deal here really. 12 hours was plenty of time for a warning. I'm just curious as to why UbiSoft pushed up the maintenance a day early...

I'm betting they pushed maintenance up so that the devs would have more time to work on all the bugs in the spring event, and not be distracted by having to stop to do maintenance. (It's what I do sometimes when I'm working on a difficult project for a client, and am having problems)

I think it has more to do with Good Friday and the Easter weekend.
