EasyPlaceMode doesn't write the text saved in the schematic when placing signs, but instead places them and leaves them empty.
Editing signs manually with the SignTextPaste option on doesn't actually paste the text but only visually displays it on the block. The displayed text disappears after changing the text in the GUI or closing it.

Any text written manually works fine, although it gets visually replaced when opening the sign GUI.

Steps to reproduce:

• Place a sign with text on it
• Save it in a schematic
• Load the schematic
• Place the sign and try to edit it with SignTextPaste on or place it with EasyPlaceMode active

This affects both sides of all types of signs and hanging signs with any block state and any NBT that are able to be edited.

Tested on 1.20 and 1.20.1 on new Fabric installations with no mods apart from Litematica (litematica-fabric-1.20.1-0.15.0.jar) and MaLiLib (malilib-fabric-1.20.1-0.16.0.jar).
In 1.19.3 and 1.19.4, sign pasting works as expected.

[Running /data command to check if the text is actually there or not]

any update yet?

they used a buggy branch when updating to 1.20, there a few annoying bugs that got introduced but at least kosmo got to monetize "his" port without having to do anything lol

I'm having this same issue, same version (and I don't want to create unnecessary threads).

Details:

• Minecraft: 1.20.1
• Litematica (Fabric): 0.15.3
• MaLiLib (Fabric): 0.16.3

SignTextPaste: True

Schematic created in 1.20.1:
Placing sign in Survival - No text. Sign shows up blank (Schematic sign text disappears). When editing, you can see the schematic text until you start editing. Typed text stays.

Placing hanging sign in Survival [off solid block] or [below and matching schematic] - Same as sign (Schematic created in 1.20.1)

Placing hanging sign in survival off sign (below, not exactly matching schematic) - Same as sign (Schematic created before 1.20)

Schematic created before 1.20:
Placing sign in Survival - Schematic Text shows. Un-rendering the schematic hides the text. Typing anything shows both texts (actual and schematic). Typed text stays when un-rendering the schematic.

And yes, hanging signs off hanging signs act differently than hanging signs off a solid block.

I hope a solution is found because I have 943 signs (and hanging signs) with text to place.

2024.01.19 Correction: Hanging signs showing ghost text depends on placement matching exactly what's in schematic (specifically, facing). I've updated the relevant text above.
