Is 100% completion possible?

I am pretty certain that the shield is missing, I will find a way to patch the game and add it to the world without breaking your save so you can get the final %.

As for the queen, her disappearing act wont hurt your completion % but it sure is darn crazy to me why she is acting up, none of the other monsters do it and they are all triggered in the same manner. ‎  I will have to figure it out!
