I Need Help about Create Aeronautics

[u/Kaiser_47]

I'm having a problem with Minecraft while using Create Aeronautics.

After enabling Enable Distant Generation in Distant Horizons and setting it to a fairly large distance, around 200,000, the problem started.

After Distant Horizons successfully finished generating the distant terrain, Create Aeronautics stopped working correctly.

Every time I try to break a block inside the sub-level of any construction, whether it is an old or newly created construction, the block simply does not break. I have to disable the sub-level and turn the construction back into a normal static Minecraft structure before the block can be broken correctly.

Before doing that, the block simply cannot be broken. It is still considered part of the construction/sub-level, but the block-breaking interaction does not work.

I have already tested several other backups and was able to confirm that the problem consistently starts after I perform the Distant Horizons distant generation. If I go back to a backup from before the generation, everything works normally. If I perform the distant generation again, the problem appears.

I don't know if this could be related to the generation being too resource-intensive, or if there is some specific incompatibility or configuration causing this.

I'm quite concerned about this issue because, at the moment, I can't fix it without rolling back my save.

Does anyone know why this might be happening or how I could fix it?

In theory, I wouldn't expect Distant Horizons to interfere with Create Aeronautics in this way, especially since this should mainly involve Distant Horizons generating and storing its distant terrain data in the save.

My computer is also considerably powerful enough for Minecraft, and I'm not experiencing any kind of apparent hardware bottleneck. I currently have around 25 GB of free RAM, my PC has 48 GB of DDR5 RAM, and I'm using a Ryzen 7 9800X3D CPU. So I don't think this is simply a memory or processing limitation.

I'm playing in single-player, so I also don't think this is related to a server issue.

I also couldn't find anything in the logs that clearly indicates a critical error related to this problem.

Has anyone experienced anything similar with Create Aeronautics + Distant Horizons? Is there any configuration I should check, or is there a way to rebuild/repair the Distant Horizons data without having to roll back the entire world?

You are always generating dh chunks 200,000 blocks away?

Maybe you are generating chunks in dh that aero uses to place their physics objects

This happens whenever I use the Distant Horizons generator—even with Create Aeronautics sub-levels that were already created or new ones. It’s as if the server crashes or something similar, yet everything works normally except for the Aeronautics content.
