I noticed, that every time I create a single-player level on a map, people add few negative votes or even reviews on it.
For example https://www.warzone.com/Map/38698-Terra-Mariana
went from Average rating: 3.7692 / 5 to Average rating: 3.375 / 5.
Are there any maps you want me to create levels on?
These maps shouldn't have too many ratings, so my interference is not insignificant (this rules out RoR).
