Based on Capcom’s spotty patch history, you might want to back up your Monster Hunter Wilds save before Title Update 1 hits
Capcom isn’t always perfect when it comes to updating PC versions of Monster Hunter games, and sometimes player save files get accidentally deleted during updates. This happened with Monster Hunter: World and Monster Hunter: Rise at certain points in their lifespan, leaving some players with corrupted save data. Thankfully, players managed to find solutions before Capcom fixed the issues, but it’s never enjoyable when your saved progress disappears unexpectedly.
