Some issues?

I've tried to do some poking around. The units that "lose" their smoke in a campaign game are armor units. Infantry and and artillery that start a campaign with smoke keep it through the campaign; armor that have it in the first battle, never have it again. This includes tanks, armored cars, tank destroyers.

I have done so as well. I restarted my long campaign as Germany twice. On the second mission of each game, all of the armor units have lost all smoke. Infantry, newly purchased units and any new core units are fine (for one turn if armor). All the 'vehicles' are without smoke as far as I can tell.

Here is a save of a long campaign, second mission after pruchase as Germany.
