I believe that you do not have all the information. I may be mistaken but it seems like you have not read our posts lately.

We have announced and explained both the map system and the DWD tokens on Steem Engine. You have written a post without accurate and complete information.

Every building you had is still there, nothing is missing. It will be in your primary base once you choose it. The additional bases are optional. You do not have to have them but many players do because that way they have more production since it is in more places at the same time. You do not have to rebuy anything. Why did you even think that you have to rebuy buildings that you already have?

You can contact us on discord in our helpdesk and I personally am available to you too if you need any more clarification, guidance, assistance etc. In the future, please read our announcements and keep up with what is happening. We always provide enough information and on time but it is up to you to actually read it. Again, feel free to contact me personally and I will help you in any way I can.
