If your redstone links have stopped receiving any signal when placed on a ship, it’s probably because of Create: Connected.
There are two ways to fix it:
Change the Create: Connected common (not server!) config to turn off “Redstone link wildcard”. This feature is the one which interferes with Valkyrien Skies’ Redstone link compat.
Make sure Create: Connected is the latest version, as the newest 1.20.1 versions should automatically adapt when Valkyrien Skies is installed to work even with Redstone Link wildcard turned on.
