Well I have encountered an interesting bug.
For the Last two turns, one of the many troop summons I am doing shows up as a commander, with VL magic paths (3D 3B)... 1st was a storm demon, then an iron dragon:

Then I summon an arch devil. not only does Furcas answer the call, but I get a 2nd Arch-Devil with stats and picture identical to Furcas, named Gravesoul:

Mystified, I equip Furcas, and then go check out Gravesoul only to discover that he has "inherited" the exact same equipment, including two artifacts.

Both devils have identical equipment, no matter what I put on them. They can be individually selected and moved, although the turn has not hosted yet so I do not know what this will do to the game. They can individually have troops assigned to them without problem.
This seems like a very strange bug! Obviously this is a long running game that was started under v2.12, perhaps that is contributing to these VL-pathed commanders I am getting for free?
Have we hit the unit limit perhaps?
