I just build a lag machine in my test world and i save it as schematica and when i try to build it the error comes up

Final checklist

• I know how to properly use check boxes
• I have not used any OwO's or UwU's in this issue.

ERORRRRRR

Apart from me not wanting to help someone building a lagmachine I also don't see a way to help you based on the information you provided.
