Upon joining a server that has a loaded script, that is also on my own client, the custom recipes appear to not exist. However, if I join a singleplayer world first then join the server, then any custom recipe will suddenly show itself, and any removed recipe will be deleted. Extremecraft and neutronium recipes are both affected by this. I am aware that somebody else has reported this issue, but that post is kinda old.

Also I can't remove any Extremecraft or neutronium recipe using Kubejs. I do not know if you would have to add comparability for this, as it was not listed on your custom recipe guide.

I have no idea about the script loading issue and am not sure how it occurred, so I am unable to fix it.

is there at least a way to make kubejs remove recipes?

I haven't seen a remove interface in Kubejs yet, I will try to add it.
We will also try to repair compressor issues.

Unfortunately, due to the endless disorder and compressor formula being added through hard coding, and Kubejs not having a deletion interface, I am unable to fix this issue.
Compressor formula cannot be imported using funnel to fix the issue.

ah, well is there at least a way I'd be able to make a datapack to change compressor recipes or extreme recipes that do not have their own json recipes within the mod itself? D..:
