Found bug: During the setup phase, you can pick up a program from the program.dir menu and then hit the restart button. This will reset the program.dir menu, but not clear the program that the cursor is holding. You can then place this unit on the board and continue setting up with a full inventory. This allows you to duplicate one of your units per battle (own 3 hack and place 4 of them, for instance).
Edit: It seems possible for this duplication bug to occur without the restart button? It's happened to me by accident twice now
Also, the level 3 store incorrectly sells laser satellites when it should sell normal satellites. The node that contains the level 5 access codes is also the wrong battle, it loads up the Sysadmin Archives battle instead of its own.
