[Issue] Current Dialogue Node not removed from list when on current node

[Sensuki]

Here is a demonstration of how the current dialogue node is often not removed from the list of dialogue options to navigate a conversation tree

 

 

Here is a demonstration of how the current node is never displayed as an option when on the current node in the Infinity Engine games

 

The current node should never be displayed when the player is on that node in the dialogue, it should only display once the player has chosen something else.
