Three SP mortars do not fire explosive rounds & one fratricidal artillery piece

[Jorma]

I gave my HQ unit an SP mortar. From that moment on, that HQ unit has only been able to fire smoke. I guess that is okay, but two other SP mortars also started to refuse to fire nothing but smoke ammo. They have explosive shells, but they refuse to use them. This problem persists from game to game, map to map, in the campaign that I play.

Another problem is less consistent. One of the artillery pieces, I think it's V1 (see the attachment), often fires at the edge of my deployment frontline regardless of the actual given coordinates. This only happens on the round zero. This has led to horrendous friendly fire incidents. This event is sort of random, I think.

The attached saved game files demonstrate the problem. The problem #1 is clear and can be seen right away, but the friendly fire issue can be a bit more difficult to spot.
