Ship Disappearance/No Collision while Travelling

[Zangism]

Description

My ship disappeared after passing a certain point. I have paused the sim and use the sable find it find it but it still disappears after walk to that point.

The only big error I saw is:
[22Apr2026 12:45:36.878] [Render thread/ERROR] [dev.ryanhcode.sable.Sable/]: Received a sub-level movement packet for a non-existent sub-level

While the entity also becomes uncollidable.

Server logs also show nothing, only a constant string of saving sublevels.

You can ping me on discord "S.K." (zangism) if you want a clip of it or for me to stream it for debugging sake.

I'm going to restart the server to see if that fixes it.

Server restart did not fix it.

Moving far away from the chunk and returning fix it... I don't know what is causing this.

Oh Wait. I destroyed some robe chains (rope connected to other blocks to create a rope ladder) that glitched off a couple of chunks before. Maybe for some reason that held the rendering/physics point while the airship continued.

I disconnected and reconnected and the rope chain disconnected (but still "attached" since the rope was not broken) and fell off.

Have the same issue, when moving past 80 blocks from the center of the sub-level i get
[Render thread/ERROR] [de.ry.sa.Sable/]: Received a sub-level movement packet for a non-existent sub-level

Nevermind, i solved it.
Changed the server simulation distance from 10 to 32 chunks, now it works.
