The problem seems to be solved, you can buy the Stug for 100CC :eahigh_file:
Ive also had this exact same problem. It said it was awarded to my armory but nowhere to be found. It seems many people had this bug since yesterday as i saw in another forum and I personally believe it was caused by a miniupdate which also changed the 20 kill challenge to a 5 kill challenge which although i don’t remember exactly what the new one wanted it was very similar to the 20 kill challenge. Im sure EA will fix this as for now just keep checking the ToW no rewards forum for answers like i have. I expect this bug will get some momentum and will be fixed shortly or the stug will be awarded to every player to avoid fixing it.
Two days ago the final stage was 50% complete. When I logged on yesterday it said completed. The STUG was NOT in my armoury and I could not progress the challenge any further. PLEASE FIX!
