Crash with Dynamic Trees and Confluence - TrunkShellBlock coredir property

[Griffenders-source]

Context

Description

Server crashes when a Confluence herb block (BaseHerbBlock.randomTick)
updates and changes an adjacent block to deepslate. Sable intercepts
the block change to recalculate physics collisions
(RapierVoxelColliderBakery.buildPhysicsDataForBlock), which triggers
Dynamic Trees to query the hardness of the block
(TrunkShellBlock.getHardness). Dynamic Trees then tries to access the
coredir property on minecraft:deepslate, which doesn't have it,
causing a fatal crash.

Crash chain

BaseHerbBlock.randomTick (Confluence)
→ Sable physics recalculation
→ TrunkShellBlock.getHardness (Dynamic Trees)
→ IllegalArgumentException: Cannot get property coredir on
Block{minecraft:deepslate}

Notes

The crash only occurs when a player is connected and chunks are being
ticked. The server starts fine but crashes shortly after a player
joins, when Confluence plants start ticking near Dynamic Trees branches
growing into deepslate.
