I think this might be my very first post! (Edit: whoops, it's my seventh I see now).
Unfortunately, the reason isn't that great: whilst rarely having trouble in the past, the last couple of weeks I'm getting more and more frequent crashes to desktop when transitioning between maps / areas. I've used Steam's 'verify integrity of game files' a couple of times now and initially that seemed to help but it's no longer the case.
I've attached some crash folders to this topic. Hopefully you can look into this, especially if others are having similar problems.
Keep up the good work, still love the game.
