LittleBigPlanet 3 freezes when I enter Manglewood Swamp

I think I know what to do to solve this issue. I'll update this thread if it works.

I think I need to update the game to the latest version. I did that when I started the game, but there were issues, so I downgraded to 1.0. But maybe it will work this time.

When I update the game from 01.00 to 01.26, the 26th package doesn't install for some reason.

Edit: I've solved the issue. It was what I thought. I had to update the game.

The game still crashes sometimes, but I can live with that.
