Same here... I upgraded 4 artifacts and checked my event total after each one. Only three of them actually gave me the 100 points (which is a bug in itself), but ultimately my event total did go up 300 points from 1790 to 2090. Then I logged out and when I came back 10 minutes later I was right back at 1790 like nothing ever happened.
This is occurred yesterday too but I wasn’t paying close enough attention to be sure it was a bug and not a counting error on my part. But I confirmed it this morning, and it’s easily reproducible and based on the posts here seems to be affecting everyone.
please advise on a fix ASAP...
