I've been trying to add a few new blocks I made to a ancient city structure. I followed a guide exactly on how to do it but in a fresh world on a fresh city it did not even try to generate the structure I made. the structure file has the same ID as the vanilla one so I have no idea why it's not working. Anybody happen to know exactly how to do this?

How To:

Your structure needs the exact same name and ID as the structure you're replacing
Ancient City is a jigsaw structure, so ensure the structure blocks are all in the proper places and recall the proper target pools/structures that the original structure uses
Ensure that you put the structure in the exact and proper structure folder where the vanilla one is located in your mod directory.
1. data > minecraft > structure > ancient city > (identify what part of the ancient city/pool the segment is in and create that folder for it

Troubleshooting:

If you have done all of this, go back through and DOUBLE CHECK that your jigsaw blocks have all the CORRECT data

Ok Great thank you. I think the issue is the vanilla model exists in the files still so I neve replaced it correctly.

I searched through the workspace folder for my mod and I can't find that file. If I use the regular folder will that mess anything up?
