Righto.
Seems to be an occasional bug with the CCT and it's smoke button. This has happened in a few games now but it seems inconsistent. The smoke button is replaced with the vampire half track's button. I don't know which one cos I have never used one...
Anyway, sometimes, if I leave the tank alone for a while (10-15 minutes) I come back to it to find the smoke button is back and working fine. Not every time but sometimes.
I am playing with Royal Engineers if that is any help. Happens at all levels and with all CCTs I might bring in.
Obviously enough clicking the button does nothing.
Also had similar trouble with the bren MMG's button ability, which just simply vanishes from the options. I haven't had this since the latest patch so I guess it's been fixed.
