I've tracked down the problem and fixed this in the latest Iceberg release (1.0.12).

The technical information for those who care: Iceberg adds a new event when advancement criteria is fulfilled (not just when a whole advancement is granted), but that event was a subclass of the standard AdvancementEvent class. That means that unless mods were specifically checking that the advancement events they were listening for were only AdvancementEvent base classes, they were assuming that users were gaining advancements when they weren't. I've fixed it by changing the criteria event to no longer be a subclass of the advancement event.

thanks，I tested it again and the problem is fixed
