Outlaws of the old west Problems on server

  • Hello people since i opened my server i have been having this problem.

    for a day the buildings that i build will stay in place and intact then after a day the doors and glass windows will hang in mid air but the buildings are gone

    i don't know what to do i have tried backing up the server but when i do that then everything is gone and reloading the backup also does not bring back the buildings

    what can i do about this ???
