There is a bug whereby I cannot seem to transfer chemicals in the relocator with the Filter module. I tested it in singleplayer and it works fine, just that in a server is does not seem to filter out the chemicals. The ID is different on both servers for the same chemical. Does anyone know a workaround?

Doesn't work on the MyM server or private?

I created a private server on my computer to play with my friends, it doesnt work. I restarted the server a few times to no avail. I have not tried it on the mym server yet.

Hm okay, can you post few screenshots of the setup so I can reproduce it?

Sure! Thank you! :)
This is the setup

This is the item ID on the singleplayer

This is the item ID on the multiplayer server

I mean which filter from this list:

What's your filter which works in SP but not MP?

Edit: Mod Filter works fine for me in singleplayer and multiplayer

The module filter

Customizable text is the one not working. The rest seems to work fine.

Then I also need the Text you are using

Cellulose

It does not work with any other chemicals as well, not only cellulose

Ok, I could reproduce it and reported it:
Dynious/RefinedRelocation#385

Thank you! 👍
