Hi!

 I'm already deploy my game and I have an issue, when there is a scene (Event) and the player press the menu key, the Picture UI appears above the whole screen, is there way to avoid it? I want to fixed for my next update.

It happens in choices and in almost every event

And here is the eventing

If you need me to provide you with more, please tell me. I'll do it without any problem :)

Yeah this is an eventing issue. You don't have any condition that forbid menu from opening when message is showing. In rpg maker, u can use !$gameMessage.isBusy() condition.
