Firstly, thank you for playing!
When you say that the settings menu didn't work - what do you mean, exactly? The way I have it set up you have to click 'apply changes' in order for the changes to take effect. Unless you mean to say that it didn't open at all. I don't know - Unreal is weird and I've had issues with that screen in particular.
Also, did you read any of the terminals? I've gotten into arguments with a friend over them over whether or not it's clear enough that they're interactable.
