The robot encounter at Reeb Marina is broken. As soon as you enter the building, the robot greets you "Hello Eugene, you brother Malcom left a surprise for you, follow me", but then the robot does not go anywehere and keep saying the default lines "Good to to you" etc
And if you go the the kitchen by yourself, the robot there is not hostile.
What was supposed to happen, you follow the first robot to the kitchen, and when you arrive the robots say "Happy birthday Eugene" and then turn hostile.
