Monster Hunter: World's major DLC adventure, Iceborne, has finally made its way to PC, but the release is not without its problems. As VG247 reports, some players have had a major issue with running the new expansion--it's been deleting their save files.

When the game opens and performs a save file check, some players are reporting, an error message tells them that "no compatible save was found"--and then the game will create a new save, overwriting their completed file. Upon exiting out of the game, this new save will overwrite their cloud save, effectively deleting their completed file. This problem has been widely reported on Reddit.

Some players have been able to recover files with a community-created save transfer tool, and many have speculated that it depends on which mods players are running. The game also changed its save data format some time ago, and it's possible that players who have not played the game in a while and are just now returning to Iceborne are having issues because of this.

Other players are reporting issues with the frame rate in Iceborne, which is currently being investigated. Otherwise, the game seems to have been ported well, judging by most player's reports.

If you intend to play Iceborne but have not loaded the game up yet, it's worth creating a back-up of your save file just in case.
