We have a theoretical discussion (no one wants to try).
I myself have tried following cause i used by accident a farm to make a barrack I converted it back and the forge didn’t cost ham to convert to barrack. But i didn’t level the barrack
We now have a discussion:
What happens if you level a Barrack (say to level 5), you level it back to forge and then again transform it to Barrack. My answer would be you get a level 1 barrack. My alliance fellow says the barrack will be a level 5 again. Has someone ever tried this?
