There is a problem with the current Excavation Association where the abyss reset is not being properly applied to the right one. This is because the reset is being applied to the last abyss explored rather than the one you've chosen.
For example, when clearing the 'Volcanic Abyss' then the 'Golden Abyss', the recently cleared 'Golden Abyss' will be reset should you choose to. Please keep this in mind when the 'Golden Abyss' opens as you use your reset.
This problem will be fixed with the next patch.
We apologize for the inconvenience.
Thank you for your attention.
