Anti Tank Gun Bug?

I have the Pak 38 researched for my engineer and i can use it in the shooting range but not in an actual battle. Are their conditions for building them or is it a bug?

in the current version, only the enginners within the enginner squad can build AT and AA.

but, there’s also a bug that does not allow you to build those said buildings. perhaps a coding mistake from devs.

i’m sure it will be fixed.

If you go into a battle or to the firing range for the first time you can place the aa and anti tank gun but if you go a second time into a battle you cant see them in the wheel. You then have to restart the game to see them again.
