Hello, another nice day.
This is currently a real burden
to move into a vessel module already installed in another case:
We must do what looks like this:
1.
In window 'Module' section 'Installed Modules' Select the module for civil or military to remove civilians or military unit has to move.
2. Then move the module in the cargo.
3. Replace the last module in the new box
4. Back again civilians or military in the module.
Now, may I can suggest this simple solution:
In the window 'Module' section 'Cargo Bay Module' 1. It selects an empty box.
2. When you then click on any module already installed, it is moved into the empty box selected.
That's it.
Simple and very effective to configure our beautiful ships.
