When loading worlds with add-ons, some of the addons keep the world stuck at the initial loading bar, and after about 5 minutes it tells me "could not load world, check internet" etc, I thought maybe some of the addons were faulty on switch, however after adding numerous addons too a world, and trying to load it failed, but if u added numerous addons and then removed one of them and then tried too load the world, it would load fine until I restarted my game and then it would fail.

Steps too replicate:

Load about 5-10 addons into a seeded or unseeded addon world.

Try too play, wait indefinitely until failure. 

Restart game and remove one addon from failed world, try too play then, it should work fine. 

Restart game. 

Try too load back into the world. Wait indefinitely until failure.

Note this also makes any world loaded too realms crash as well with a "disconnected error"
