I have a catalog choice, Panzergrenadier platoon, that must be taken 2 or 3 times in a roster. That catalog choice has a transport option for the HQ section, Kfz field car, that must be excluded if you upgrade the Kfz 70 truck in the squad section to a 3-ton truck. This works normally, but there is an interconnection from one selection to the next. For example, if I take 3-ton trucks in the first Panzergrenadier platoon, it triggers an error for the Kfz field car in the second Panzergrenadier platoon.
