Me and a few friends had one of our friends make a world so we could play Minecraft together. We decided she doesn’t go on enough and we don’t wanna wait for her to come on so we can play, so she attempted to export her world to us so we could play separately (we downloaded the world on to our computers). That didn’t work out, so we decided to return to what we were doing before by following her into her world like normal. However, now we cannot do so and any time we try to join it says “Outdated Client”. Not only that, but sometimes when our other friends try making their own worlds, it doesn’t show up that they’re playing in a world at all. Is there any way to fix these problems?
