Crash at EndPlay Attempting to call an unbound TFunction! #28

I'm receiving the following crash when using GES in Unreal 5.1.1 only on EndPlay

Assertion failed: Callable [File:\EpicGames\UE_5.1\Engine\Source\Runtime\Core\Public\Templates\Function.h] [Line: 596] Attempting to call an unbound TFunction!

Do you call use GESUnbind All Events for Context to balance your bind calls? https://github.com/getnamo/GlobalEventSystem-Unreal#unbinding

While technically optional, there are some cases that can slip past the auto-unbinding system and cause crashes like this so I recommend using unbind calls to balance your bind calls on endplay callbacks.

@getnamo Thanks that's how I fixed it.
