Game crashes when attempting to generate new chunks that contain the final tower structure in Twilight Forest

Context

When attempting to generate chunks that contained the final tower structure in the twilight forest the game would consistently crash, disabling sable and aeronautics fixed the crashing issue. Interestingly, after logging out in the chunks that would previously cause the crash with the mods disabled, then enabling the mods and relogging into the world, the crash would not happen in those chunks, even after un-rendering and re-rendering them. It is only when I approached a new not yet generated final tower would the crash happen again.

I had the exact same crash, caused by the force field block I think.
A rudimentary analysis from claude spat out the following:

1. Twilight Forest loads a chunk and places its ForceField blocks during postProcessGeneration
2. ForceFieldBlock.getShape() reads neighboring block states to determine its collision shape
3. Sable's LevelAccelerator intercepts that block state lookup and fires its physics pipeline (RapierPhysicsPipeline.handleBlockChange)
4. The physics pipeline then tries to bake collider data for the ForceField block, which requires calling ForceFieldBlock.getShape() again
5. This creates a recursive ConcurrentHashMap.computeIfAbsent call — Java throws IllegalStateException: Recursive update and crashes

couldn't find a method to exclude block ids from sable control
