[Bug]: Vanishing Chains/ Rope

[Calais0001]

Checklist

• I am having issues with the Fabric version.
• I am using the latest version of Connectible Chains.
• I have looked for similar issues.

MC Version

1.21.4

What is the problem?

A bug happened!

Description:

Chains and ropes vanish, likely when chunks are unloaded and reloaded. I have never seen them disappear in real time. This occurs in both Singleplayer and Multiplayer. I have been using the ConnectibleChains mod since version 2.5.0, initially in my Singleplayer world. We're currently using the latest version (2.5.2) on our Fabric 1.21.4 server.

Reproduction Steps:

1. Run a Fabric 1.21.4 server with the latest version of ConnectibleChains.
2. Place a few chains and ropes.
3. Unload the chunks (e.g., by moving far away) or restart the server.
4. Reload the chunks by returning to the area or logging back in.

Expected Behavior:

• Chains and ropes should persist after chunks unload or after a server restart.

Actual Behavior:

• Chains and ropes vanish when the chunks unload and reload, or after a server restart.

Relevant log output

There are no errors related to this mod. However, I will share our mod-list to ensure no incompatibilities:

There are no errors shown in the logs when chunks load where chains/ rope have vanished. Nothing client-side either.

Similar to #68?

[Calais0001]

@legoatoom Yes, it seems so.

• Chains/ Rope seem to disappear when going from one chunk to the next (I used F3+G to confirm).
• I checked [Bug]: Chains randomly "break" #68 and saw some people post errors from logs that might help. I'll be on the lookout for these.

Playing 1.21.1 using version [2.5.2] on a server with a friend, it happens all the time. https://imgur.com/a/xkX5TaE

EDIT: A few times I came back and the lead item was on the ground.

[legoatoom]

I have been trying to reproduce the error. But I have not been able to.
I might release an update with more logging to be able to find what is the reason chains are destroyed. As items do appear on the ground.

Meanwhile, can you check. For the chains that are missing connections, are there perchance two knots on the same fence/wall?

@legoatoom

If I understand correctly. Yes, I have 2 chains connected on the same fence.

To my knowledge. It still only seems to happen for chains going from one chunk to the next, and It's a possibility that it occurs when there's 2+ chains/rope on the same fence too.

More logging may help, I'll be able to send some logs over the moment I catch a chain that's vanished. I'll send our server & client logs. If its some particular error when a chunk is loaded, then it should catch when that chunk is loaded(?).

[legoatoom]

Not two chains connected to one fence. The knot on a fence, there might be duplicate entity on it? Two on the same fence, you might see it if you break it as you have to attack it twice with a shear.
I might send a jar this weekend with more logging if I have time.

@Calais0001 Thank you for your patience.
Here is a custom version of the mod with more logging in a zip file. If you wish to see what is different in the code, see the commit reference below this comment.
Hope it shows why it might be vanishing.

@Calais0001 I have not received any update, can I presume you are not having any issues?

Legoatoom, it still not working. Some ropes are still disappeared even I’m on 1.21.4
