Sometimes when you try to enter a portal, you can get an error that says "Cannot Join World, Object reference not set to and instance of object".
Portals seems fine before you enter it. Then you get the pop up with the error. After that the portal is blank without info and you can't pass through it. Selecting it and looking at the info still shows an instance as expected.
I haven't found a way to replicate this. And i have been experiencing it for a while on different versions.
