Original title
Redstone Torches Can Break, When Reloading The Area
Original description
Occasionally when you reload an area of the world, redstone torches can break in a weird way. This typically happens when they are powering redstone dust, and the torch its self can be turned off bu the redstone circuit.

Its a hard one to explain, but it happens pretty frequently on realms, and it breaks LOADS of redstone contraptions!

Below you can find an image of a auto-sorters clock being broken from this bug, and a full demo in a video i made!
