Welcome to the Make community!
You can use the Make DevTool to remap module numbers, or you can export your blueprint, find and replace using a text editor, then reimport your blueprint.
Hope this helps! Let me know if there are any further questions or issues.

P.S.: Did you know, the concepts of about 70% of questions asked on this forum are already covered in the Make Academy. Investing some effort into it will save you lots of time and frustration using Make later!
