I lost one if my Colonies, it is a region called RGN-970. It should be under my account name. If there is anything you can do, that would be great. The reason I lost it is because I got an SSD for my PC and I reinstalled my OS, without backing up the region in my colony.
EDIT : Forgot to mention this, it should be about 2 months old, somewhere around there.
Thank you for reading this, have a great day!
