From time to time, users report to me the following:

Now, from the checks I did, it looks like the reward is awarded only once, but I'm not 100% sure about it.
Of course, I just set up one event, and it usually works fine, awarding people only once/showing the notification only once, but I've got at least 15 reports of this type in all the months I've been using your add-on.
I don't think I can provide steps to replicate this issue as it happens randomly, but I'm sure the screenshot above explains it all.
