The Bug
Fences can fail to connect properly in Mineshafts. Might have something to do with the chain connection to fences.
Reproduce
Seed: 6410084222843938435
Coords: /execute in minecraft:overworld run tp @s 250.24 24.00 1861.10 -1486.34 15.90Observed Result
The fence wasn't fully connected
Expected Result
The fence would fully connect
Does this qualify as the same issue as MC-236433?
