Describe the Bug:

First off, thanks for the update to enable customization of the block that is being used!
however, this broke the disabling of placing blocks outside of your chunks

I double checked on the defaultconfigs and on the save config that block placement is set to false

[Gameplay]
	#Can blocks be placed outside spawned chunks
	block_placement_allowed_outside_spawned_chunks = false

it seems as if this latest update broke that feature

I am not reproducing the issue - I set block placement allowed to false and created a new sealed world (with the sealed block set to gold) and I could not place on the sealed chunks.

Please note that the defaultconfig and mods menu only affect new worlds. After a world is created it has its own config in its serverconfig directory. Are you creating a new world with block placement disabled? Otherwise, I'm not sure what is going on.

Newly created world (using a custom block, created with KubeJS as block)
as you can see, the defaultconfig is set to false

(don't mind the block breaking not working, thats caused by a diffrent kubeJS script)

EDIT, couldnt replicate it on a testing instance with just Chunk by Chunk, i will report later what causes it

Closing for now due to lack of information.
