I have two things confusing me...
1. 4th NJ Vol. (5 elements) in Washington DC has a Command Usage of 16 if you hover over tab, but lists 4 if you hover over unit. The penalty is 35%, so it seems to be based off the 16.
2. In Manassas I have Runyon's 4th Division (only 2 elements) and the 4th Division HQ? Runyon's 4th can't recombine with other units, despite having a Command Usage of 4, like a HQ.
I am running 1.02 patch.
Have attached save.
