I'll start playing this locally to test out the changes. Got a few questions in the meantime.

There's still a few leftover logger statements, overall nice work :)

Can't really think of anything than changing the api of Listen to include a once = false parameter

We may need to do a bit more for this, like create a listener group that allows storing a set of listeners that can be disconnected at once. For this case, we listen to 2 listeners and disconnect both when received.

Example:

var listenerGroup = new ListenerGroup(maxCalls = 1); // MaxCalls may make it more clear this event can only be called once.
listenerGroup.Listen(event1, (...) => {
	...
});
listenerGroup.Listen(event2, (...) => {
	...
});
