I've just started a long campaign as Russian and although I have a section of KV1's that can be placed and do everything they should they have no icons, they can move shoot everything except actually be seen. Is this some wonderful Russian stealth gear lol ?
I'd attatch a save game if I could work out how to
At the least, what was the date of purchase in your campaign? Should make finding the specific unit easier, and see if it can be reproduced on other installations.
I just set up a battle for 6/42 and my KV1cM1942's, KV1-M1941's, KV1-Ekranami's and KV1 flame tanks (KV8's actually) all show up.
So which unit are you talking about?
One suggestion, before actually starting the game you get a screen with game options. In that screen go to 'Misc' and click on the 'No' behind 'Show ID numbers'. It should go to yes now.
When in a purchase screen in the game you should now see the specific unit and formation ID numbers. By using these a lot of confusion can be avoided.
I got the same as narwan, all 4 types had icons for me.
One option would by try a reinstall, see if something got lost between install & patching up the game. Unless you've modified OOBs,etc shouldn't loose anything in the process.
