Free Mortar? and where are my Panzers ?

[CCCPeter]

Good day soldiers,

although very much enjoying the Mowas game (as a noob), there are some thingies i can't solve.
Maybe someone here can help out, cause i just can't find the answers with pressing buttons or with google or at forums.
I play sp skirmish on a pc without www for now, so practicing with other minds is no option.

Now i am playing the MarketGarden skirmish (easy, german side).

1. When i placed sandbags around a mortar team or hmg, i cant get the team out of there.
I cán get the men out, but not with the mortar or hmg. Sandbug or me stupid ?

2. When i reach the point that i get additional resources, i cán order the StuG III, i pay for it, the timer runs,
i get the announcement it's arrived....only to find nó StuG.
Almost the same go's for the veteran Tiger I. I get 1, but the remaining 3 that are available won't show up when ordered and payed for.
Wó sind die Panzers verdámmt nochmal
BTW, all the other goodies arrive normal.

3. Not really a problem (it kinda reflects reality....) but sometimes i noticed that soldiers lose their main weapon although they are in good shape and have all their stuff (ammo, gear)
No way that i can find it, not even with the "show items button".

4.Sometimes my truckdrivers dissapear? I than quickly assign some soldier to take his place, but how can that be ?

I even wonder if such "problems" can have anything to do with the hardware ?

Hoping to get wiser, i great you all

Peter
