If you replace, for example, iron ore with shroomlight, you will see that the block will need to be manually updated (punching a block next to it) for it to start emitting light.

I don't know if that's in the scope of this mod but it'd be nice to be able to add light emitting blocks that way.

Should be fixed in latest! Try this: https://www.curseforge.com/minecraft/mc-mods/block-swap

And let me know if it works or not!

Wow nice I will test this!

did it work?

I confirm in the use case I told you about that it indeed worked.

Thanks a lot
