WILCO
and, concerning the afformentioned BUG REPORT :
Ok, to report back. I deleted the Red Devils to see if this was the prob (as everything I clicked on was turning into one of these soldiers) yet the problem has persisted with the 101st Airborne.
It seems this bug only happens if I add the squad using the group menu. If I do this, then subsequently click on, say, the officer, it will change this to a Garand Soldier. Consequently, you have to swap the troup type back every time you click on a soldier to make alterations to it.
The workaround is obviously to make my own groups, but I thought you might like to know about this.
All the addons are great... teething probs are to be expected!
