It's still showing that I've earned 600/1000 currency and the last time I did a puzzle was at the last event. I did mention suspected issues with the puzzle not resetting currency during the last event, but I honestly wasn't paying close attention to when I played last versus when it was resetting to officially pursue it (because at that point, it seemed to eventually reset itself even if it seemed to be more than 24 hours).
Right now though, there's no denying there's a weeeeee bit of an issue.
And yes, I've refreshed cache, etc., etc.
TIA.
