For The Pioneers: Surviving Desolation players, this is a guide to explain how to upgrade objects within block modules with pictures
After which this menu should pop up with all your installed objects (you must first build and install an object before you can upgrade it)
Left click the object you wish to upgrade and here you will now see the selectable upgrades.
Hope this helped someone!
Please note that as of right now you cannot upgrade the sizes of blocks! Even if it is difficult to at the beginning of a new game, try and make every block the biggest it can be.
