Double posting because I found something important-ish.
I decided to stop by the Hardlight server and see what was up with the iron farm. I had spawned right in, so I might've been surveying it before. The iron farm had clogged up from golems sticking on the edges of the "drop chute," so I expanded the hole and built retaining walls out of stone fences.
As part of the maintenance, I climbed up to check the top part, where the cane farm was, there, too, they were constricted, but placing some water blocks on the E and W sides resolved that.
This is when I noticed that the cane farm pistons were not actuating. I later come to find out that recent server changes
prevent pistons from moving blocks outside of land claims. Somebody will have to make a claim in that chunk(s) to get the cane farm back up and running again.
I also noticed, that STILL the cane farm is full up to the brim. Even the ****ing hoppers that transport the cane to the chests are full up.

[Edit] I managed to get a water conveyor system set up to transport all of the cane from the farm down to the control room. Still need the pistons to be fixed before the farm can get running again, however.
