No crash report, just stuck and not generating any more chunks.
My computer is 5900X with 64GB, and I have the render distance set to only 12 chunks. I don't think it's an issue with my computer's specs.
Please fix it, and I also hope you can address the issue where save files do not run properly after removing this mod.

What profile? What kind of city did you generate? Any special settings?

The second issue can't be fixed. That's just how Minecraft/Forge works. Lost Cities is worldgen and that's baked into the world

And it is related to the world seed. Some seeds can generate more chunks before getting stuck, while others can only generate a few chunks (like my main save)

I have quite a few mods installed. I’ll send you the logs later.

Also what version of Lost Cities?

I tried several times with normal buildings and many times with tallbuildings, as well as versions 7.3.x, 7.2.x, 7.1.x, 7.0.4, and the same issue occurred every time.

Sounds like a conflict with some other mod. What kind of worldgen mods do you have? Also can you give me the latest.log?

Hey.I seem to have found the problem. I discovered that the chunks won't load when The Lost Cities is installed together with Tectonic and Artifacts. However, installing any two mods, it works fine and generates normally. It's only when all three mods are installed together that it gets stuck. Can you go test it out? I've put their links below
Tectonic: https://www.curseforge.com/minecraft/mc-mods/tectonic
Artifacts: https://www.curseforge.com/minecraft/mc-mods/artifacts
The seed I used: 6513396509080690677（with Tectonic）
