Signs are broken

[Cathay3520]

Description

Cardboard mod 1.20.4 breaks signs.
I am aware of the 1.20.4 version of Cardboard is said to be broken, just bringing this up so the situation gets noticed

Steps to reproduce

Assume that the Fabric (Cardboard) server is set up.

1. Put Fabric API, iCommon Library and Cardboard 1.20.4 mod into the mods folder.
2. Start the server.
3. Put down any signs, of any wood varient, or any hanging signs of any varient.
4. When the text editing window is exited, you get literal{} on each line. i.e.
   literal{}
   literal{}
   literal{}
   literal{}
   If you have typed something, for example you've typed "test" on the first line, the output is:
   literal{test}
   literal{}
   literal{}
   literal{}
