The farther I get in the game, the more often it just crashes. Mostly it's right after I finished a mainquest (or a part of one). Used to be that it "only" crashed once a day, but today it happened five times already. It's starting to get old. Sometimes I have to play up to the last 10 minutes again, and that's not even counting re-starting the game. And the issue is definitely not with my PS4, since it doesn't happen with ANY other game, and my software (both PS4 and game) are up to date - I checked.
