Hello! I was having the exact same problem as you and after consistent digging through forums I found a solution. What I did was within the folder where you have your game and configs(should be called game server or something like that), make a folder called t6r first. Then within that folder make another folder called data. You then want to put your configs in this folder. This worked for me, let me know if it worked for you!
