Hey

I play with Connectible Chains, Optifine and other mods on multiplayer server.
My friend have put a chain between two cobble walls and if I am connected to the server after the chains are put, I can't see them but my friend can.

Here a screenshot with a chain placed before I connect to the server on the left , and chains placed after I connect on the right.

A last thing, when I attack an invisible chain, I can ear chain sound.

1.16.5 is no longer supported, won't fix.

sad that there is no fix yet :(

Bump, same issue here

Same problem here :c
