If you are walking through your build and see missing blocks where there should be blocks, it is most likely due to the version difference between the downloaded build and the server you are trying to upload it to. It is highly recommended to read the version compatibility before purchasing and/or downloading a NetherixStudios product. For a more personalized support create a ticket in our discord, describe your problem.
Good to know: Check the downloaded file in the first. It is possible that you already have a version of the map for your server version in the downloaded file
