I am the dev of Bumblezone and someone over at Prominence Forge modpack sent me this crashlog:
BEE_1.txt

Now I have no idea how to even debug this as no one else has reported this issue and breaking my block works just fine and shows the breaking overlay with no issue. All I see is CodeChickenLib is in the stacktrace that might be causing my model to well, not have the model anymore for whatever reason
codechicken.lib.render.block.CCBlockRendererDispatcher.renderBreakingTexture(CCBlockRendererDispatcher.java:88)

The Bumblezone repo if you need to look at my code:
https://github.com/TelepathicGrunt/Bumblezone/tree/1.19.2-Forge/src/main/java/com/telepathicgrunt/the_bumblezone/client/bakedmodel

I was not told exactly how the user managed to get the crash to occur.

closing as modernfix seems to be the root cause for causing my model field to be null
