Nothing says 'Good Job' quite like a shiny gold star, so it's understandable if you're upset by not receiving your Stars for Events.
The good news is, the latest update has fixed event stars! Just make sure you have updated to version 6.3.1. Please note, this will only fix Stars for events moving forward; it will not fix events that were already affected.
For past events, all reports of this are purely visual - you should still be receiving the items and Badges for the achievements. If you check your Inventory and notice that you don't have the Badges you've earned for the Event, please send us an email (use the 'Submit Request' button) with the following info:
- Your current PlayFab ID (tap menu > Connect > bottom left)
- Screenshot of your Events tab (tap menu > Adventures > Events)
- Screenshot of your Inventory
