Since 2.2 when either mounting the cannons in CM or the magitek in Praetorium, it displays an additional hotbar on my screen which seems to be uneffected by any of the settings. I wanted to hide it but can't seem to figure out how. In the HUD layout there isn't anything in the place this hotbar pops, so I can't even shrink it.
It is not a big issue cause it is just CM/Prae but if we ever get a similar mechanic it'll probably annoy me.
