I am uncertain if this is a bug, or even if it is related to your mod. But I noticed "residual" redstone signals around places I had previously placed circuits. Then yesterday I came across the situation below which visualized it.



i.e. after removing the circuit the lamps around the previously powered one don't update.
Apologies if posted in the wrong place.

Thanks for reporting this! I'd like to call this a vanilla bug, but if you do the same thing with vanilla redstone, it works as expected. It's just a vanilla oddity that "quasi-connected" neighbors blocks don't get updated when a block's redstone signal changes. Somehow, I need to force each neighbor to update its neighbors when the block entity is broken.

Now fixed in all MC versions, including the new 1.19 version.
