4.13.2 de-bugging

[Tennie]

I've been having a problem with the intervalometer settings on the bombers equipped with them:

Although I've tried several different hotkey settings, when I try to use them, they don't seem to work. Not only do I not get a popup message showing the new settings, but the dials on the intervalometer don't seem to move. And yet, in some 4.13 videos that I've watched, both things are shown to happen.

Keep in mind that I already have the basic bombsight controls (altitude, speed, up/down angle, left/right angle) already set.

Is there something that I'm missing here? If so, I would appreciate it if you could help me with it!
