Callback was already called

See original GitHub issue

After updating to 3.0.0, I get an Callback was already called error. I reverted back to 1.4.0 and it runs again without issues.

Here is the callstack:

I’m currently at my day job, but I’d be happy to see if I can reproduce the callback firing twice and drop a PR later today.
