I noticed when using C2Me, it would repeatedly warn me about stronghold positions initialized, c2me dev is telling me a mod(in this case your mod) asks for stronghold positions maybe, therefore slowing down chunk generation speed. Please fix if possible ^<^

Can you post some logs showing the warning? I'm not sure about any point in the code where it would be recalculating stronghold positions.

sadly I cant send logs since I deleted the pack I was doing stuff in, but you can simply install c2me and yungs better strongholds mods and you will see the logs spammed while new chunks are generated.

Closing due to lack of information. Feel free to open a new issue with more information (logs, version numbers, etc) if this is still an issue.
