The recurring bug/glitch has a simple workaround! Use Hotkey "W" to order partisan to retreat to Zis. Use Hotkey "Y" to order Partisan to set boobytrap! I suggest that the Hotkey for booby trap be changed to a character preceding W in the alphabet for the next patch.
The implication here is that the 4x3 GUI is really a 4x3x2 GUI. IE the interface is not limited to 12 functions, at least 24 functions are available to the interface but 24 different Hotkeys would be necessary to access them all!
