I'm not entirely sure what's causing it all I know is that theres a chance it shows up when you look at world then switch over to another, it sometimes (not always but a good majority) shows the instances for a world you were just looking at instead of the current one. Now it doesn't always happen, sometimes it does load in the instances for that world but a majority is that when you look at one world then back out and look at another world only the instances for the previous world show up, you can go to the random instance that it shows when you open it but specific instances do not show up for said world, only the ones before
