[Error] FramedBlocks adjustable double blocks + ModernFix

[kotovski244]

Bug Description

On Minecraft 1.20.1 Forge 47.4.0 with FramedBlocks 9.4.2 and ModernFix, an error occurs when rendering the following blocks: framed adjustable double slab, framed adjustable double panel, framed adjustable double copycat panel.

Expected Behavior
Blocks should render correctly in the world and as ghost preview when aiming, without errors or crashes.

Reproduction Steps

Steps to Reproduce

1. Install FramedBlocks 9.4.2 and ModernFix.
2. Hold one of the listed blocks in hand.
3. Aim at a surface.
4. An error appears: first ModernFix outputs an error message, and if interaction continues the client may eventually crash.

Log File

Log (excerpt)
java.lang.NullPointerException: Cannot invoke "BakedModel.getQuads(...)" because "model" is null at xfacthd.framedblocks.api.model.util.ModelUtils.getAllCullableQuads(ModelUtils.java:404)

Can you send the full log file and crash report? I don't think anything major changed in FramedBlocks or ModernFix's model logic recently, and many packs use both together, so it'd be weird for this to start being an issue now. I suspect something else went wrong and this is just a symptom of that issue.

Please note: the log contains some unrelated warnings/errors from All The Mods, because I customized the pack for my own use. These are not connected to the issue I’m reporting.
