The title. I opened up my world after updating and can no longer use the item wireless accessor. Everything else seemingly still works, can't speak on the fluid wireless accessor, as I am not using it currently.

did you try clicking the master with accessor again?
does it work in another world?

It does work in a different world (singleplayer). I am using this on a server by the way. I did try and click the master again, and I tried breaking the master, replacing, and clicking it again.
