The developers of Silent Hill f have addressed a specific issue with the PC version of the game. Due to an error, some Steam users were able to access content from the premium edition, as well as pre-order bonuses, even though they were not entitled to it.
Studio NeoBards has warned that it plans to release a patch that will remove the bonuses:
"We are investigating an issue in the Steam version of SILENT HILL f where bonus content and pre-order materials not included in the edition purchased by players are temporarily available. A patch will be released soon."
