When I logged on a few minutes ago, I was astonished, that none of my sessions should have expired over night, because there was no alert. Then I went to the Training Center, and a few of my batches WERE done. It's possible, that I forgot about setting an alert for one training batch but not for all of them!

Alerts for games, buff expiration, Forum group mention came in.

edit:

o.k., so the alerts, that did come in, must have happened earlier. I've just got a shop discount buff, but no alert is coming in.

I suppose, alerts are broken again in general?

I haven't done much that requires alerts besides Pet Zapper yet, but its alerts aren't coming in anymore as of Sunday.

the "lost" alerts came in 3 hours ago.
