Road schematics lose Player Head textures and Banner patterns during road generation

Server Version

1.21.11

Describe the bug

Actual server version: 26.1.2
I selected 1.21.11 because 26.1.2 is not listed in the form.

When PlotSquared generates roads from road schematics, Player Heads and Banners lose their custom block data.

After regenerating the world:

• Player Heads become default Steve heads.
• Banners lose their patterns and revert to their base appearance.

However, the generated schematic files seem to be correct. If I manually paste the same schematics from genroadschematics/ with FastAsyncWorldEdit, the Player Head textures and Banner patterns are restored correctly.

So the issue seems to happen during PlotSquared road generation, not during schematic creation.

This may be related to #4026, but the issue still happens on 7.5.13-Premium.

To Reproduce

1. Create a PlotSquared world.
2. Build roads containing custom Player Heads and patterned Banners.
3. Run /plot createroadschematic.
4. Delete the world.
5. Generate the world again using the generated road schematics.
6. Check the generated roads.

Expected behaviour

Player Heads should keep their custom textures.

Banners should keep their patterns.

The generated roads should match the original roads.

Example Player Head block data:
