So I got an add for hammer jam and I decided to check up on my base again after like a year of not playing and was pleasantly surprised at the game changes. I had to attack my own base with my army because I had been away for so long the villagers thought I was a goblin lol. And then, the real magic happened, my builder had decided to upgrade my wizards towers, archer towers, cannons some walls and even my heroes by like 5 levels. I also had a ton of resources in my loot cart. This was great and I just want to thank whoever implemented this into the game
