There has been an issue with the auto-combat rewards with the Excavation Association update.
The issue occurs when the auto-combat team and the Excavation Association team overlaps. The resolution asks to either separate the auto-combat team or fix the auto-combat team.
We apologize for the inconvenience, but please go on excavations before going on auto-combats.
This issue will likely be solved with the next update.
Thank you for reading.
