For a little while now, everytime I place a beacon, it’s beam is invisible to anyone standing more than around four chunks away. I’m guessing that this is because most sub-blocks disappear after a short distance in order to run smoother. However, this negates the primary purpose of a beacon—to act as a beacon. Beacon beam ranges should last at least as long as the render distance of the world.

Note with the attachment that I wanted to include a video but was unable to with the 10MB limit.
