If an expected UI element or button is no longer present in the game view, it is likely that it has just been hidden from the view. Depending on which UI element exactly went missing, it can be shown again by different means:
- Info Panels in the upper left of the game view can be toggled on and off using the buttons on top of the info panel area
- The buttons to the left of the central HUD element (Autopilot, Tactical Overlay etc.) can be shown or hidden by the "<<" or ">>" arrow symbols
Many UI elements have further settings to hide or show certain bits if the UI without hiding everything, which can usually be found within the menus of the respective UI parts.
