Hello, I bought the premium of My Colony few years ago and I can't find the way to redeem it on steam. I know I should have a file to get the key on steam, but I can't find it anywhere.
What am I supposed to do?

When you are in the late part of your game, if you want completely reorganize your base, it will be a problem. Effectively, with a lot of colonist, it is dangerous to sell all the food, water and housing buildings. It is for that I suggest a new window where the time doesn’t pass with the map less your buildings and with a toolbar. You don’t have to buy your buildings again because they will be in this toolbar. And it will be faster than construct and delete buildings one by one.
