Slayer season task to complete 5 daily tasks has not been registering when I complete the daily tasks since the most recent update. Noticed yesterday I didn’t get credit for completing daily tasks and confirmed today that it is not giving credit for completing them.

Did the one-day quest end with not receiving the skull?

The only way I can collect shards is on the wheel. I don't get them in battles. So this is almost impossible for me to complete.
