1.16.3 EventBus crash

[Turtledove]

So in a codebase that was working perfectly fine just last month, I come back to this crash I just can't seem to figure out why it's happening:

Anyone have an idea what it might be?

Post your code.

My guess is that you're registering an event handler to the wrong bus.

I just reimported my gradle project and now it works.
