Hello,

I have an issue with transitioning between states with event condition. I have this transition and it works fine.

But if I add “Required Event to Enter” it stops working.

Event is not consumed on transition, and it is 100% same event, so I really don’t know what can be wrong here.  
My state tree:

So, I accidentally solved this, but I have no idea why it works. Adding empty sibling state is solving an issue. So everything is the same except my state tree look like this. Weird fix, but ok.

Same thing. Simplest example not working.
