Process_cq seems to be working for me, but create_unit doesn't. I've triple checked the Id's for the units I've tried to make, and even though the whole command is typed out correctly, the console says it wasn't recognized.
If this makes finding an answer any easier; I'm playing as mordor, and I'm trying to get myself "Sauron's Will" units. (I did a test just to make sure it wasn't just 'Sauron's Will', I can't spawn any other units)
I feel kinda nervous for asking how to cheat on Total War; but I'm about to retake the Misty Mountain territories from some really beefed up Dwarves. I honestly would've attacked by now, since my strongest force is at their front door. Luckily, I convinced myself to send a spy who with a lick of luck managed to infiltrate them. I was horrified at the amount of Generals, artillery, and dragonslayers. Now, I don't know about the other Mordor players; but I'm paranoid about losing Sauron (This is partially because I'm a big fan). So, my conclusion was to hop into the helpful arms of the Total War center and ask them why I can't spawn "Sauron's Will" units to reinforce Sauron himself. So, eh- A little help, sire? For a poor old Dark Lord of Mordor?
