Duplicate Events Passed to Plugins

[Databean]

The series of if statements causes some handlers to be double-added, e.g. using something like handleAbilityEvent will get matched both by the specific if on line 207 and the catch-all if at line 211 at the end, and be added to the handlers list twice. Events passed through the handlers will then get passed to those handlers twice.

Ah, good catch. AbilityEvent should be an abstract event type for this to work as intended; currently it is not. I'm not sure how I overlooked this issue. I'll have to patch the events and properly separate the two concepts.
