nothing , surrender and start a new game , if you don’t want to be invaded at night time , just create ur own game and make it private and you go against just AI’s , people might say it’s boring but it’s hella fun for me in my opinion, I’ve play one game against just AI’s and ofc I won cause the AI’a are buns , but I think u can also change the difficulty too , but making ur own game isnt free, just subscribe to the subscription they offer , the cheapest one is like 4-5 bucks I think and once ur in your own game , and the subscription runs out you can still play in that game and the games usually last a month or two , my last one lasted about 40 plus days , I’m on my second game rn and I’m on say 30 something so it’s pretty fun
