Hi!
I was having some issues with terraforged lacking some structure generation. I was following the project's issue tab and I stumbled upon this issue.
I was able to replicate it by testing a few worlds with and without the supplementaries mod installed, using the same seeds for each world.
This is without the mod running, on these seeds using the terraforged world type.

And this is with the mod running, on the same seed using the terraforged world type.


I'm not sure what log file to post, since it's not technically crashing. I'll help out any other way I can.

I'll test out your suggestion, it's a very puzzling bug because it doesn't happen on every world, but in the worlds that it does happen, i can reproduce it with 100% accuracy.

Worldgen will never stop haunting me won't it XD
Ok so let me see if I got what's wrong: basically some structures don't spawn with the mod installed or spawn at different places.
I have no idea why this would happen since I'm doing very little with world gen and I'm specifically not registering my stuff for terraforged world type (since I was told it does that itself) but to try something out try disabling way signs and wild flax since those are the only world gen stuff I'm adding. IF that doesn't work then I have no idea.

Ok, I've made some progress.
I've tried your suggestion, but it didn't help. However, disabling the mod and entering a world that was created with supplimentaries running and terraforged world type selected, then using the /locate command, I was able to find the structures without problem. Could it be some issue with how structures are tagged? I'm not a programmer, I'm just guessing. Hope this helped!

EDIT: There's this issue I also found in the end reforged gitlab, if it helps

well regarding that issue you posted I'm actually already using that same exact code since I followed Telepatic Grunt turorial so I don't think that's it. One thing I would like to know is if when you use the locate command, the one that fails, does it take a second to give you a reply or is it istant?

It's instant.

oh so that means it's not even getting added
