As excited as they may be, PC players might want to wait a little longer before trying out Monster Hunter: World's newest expansion, Iceborne. There are confirmed reports that the DLC might delete your old save file if you're not careful.
First reported by VG247, when the player boats up the game after getting the DLC, they might get an error message saying that there is not a compatible save game available. From here, they have the option to start a new save that IS compatible. But if they do that, the new save overwrites the previous existing save instead of making it a separate save.
Capcom is aware of the issue, too. In a statement to Polygon, they stated that they are aware of the issue and are actively looking into a solution.
Currently, players speculate that mod incompatibility might be the issue, or possibly that these games are missing a particular update that changes how saves are formatted. Regardless, everyone recommends saving your game to the Steam Cloud before trying the DLC, just to be safe.
Iceborne was originally released on consoles in September of last year. It only recently released for PC players as well. The expansion has received a great deal of praise for its fun and interesting world, monsters, and weapons. You can even fight with a giant chicken drumstick as a weapon!
