[Forge/Sinytra Connector] Chunky Chunk Preloading Stuck When Using C2ME

[sj-3-sj]

Describe the bug

When using Sinytra Connector to link Fabric mod C2ME to a Forge modpack, Chunky fails to preload chunks—progress gets stuck indefinitely with no error prompts. Troubleshooting (restarts, world regeneration, different C2ME ports/forks) did not resolve the issue. This may stem from thread synchronization conflicts between C2ME's async chunk loading and Chunky's preloading logic, or compatibility gaps between C2ME, Sinytra Connector, and Forge.

To Reproduce

Steps to reproduce the behavior:

1. Install a Forge modpack (specify version in Runtime info) and add Sinytra Connector, C2ME (any tested port/fork), and Chunky.

2. Launch Minecraft and enter a new or existing world.

3. Open Chunky GUI, configure preloading area (e.g., radius), and start preloading.

4. The progress bar freezes (e.g., 0% or low percentage) indefinitely—no errors, game may remain partially responsive but preloading cannot resume.

Expected behavior

After starting Chunky's preloading, the progress bar should advance normally and complete successfully. Preloaded chunks should load properly, matching Chunky's normal behavior when C2ME/Sinytra Connector are removed.

Checklist

• I am using the official version of the mod. (Mark for official C2ME; unmark for ports/forks)

• I tried the latest development version but the issue persists.

• I searched for similar open issues and found no existing report.

Additional context

1. Failed troubleshooting steps:

• Restarted the game multiple times (client/server if applicable).

• Regenerated worlds and tested preloading in fresh environments.

• Tested different C2ME ports/forks—all had the same issue.

• Adjusted Chunky’s worker thread count with no improvement.

2. Key details:

• Issue only occurs with C2ME + Sinytra Connector; removing C2ME fixes Chunky.

• Possible causes: C2ME/Chunky thread conflicts or incomplete Sinytra Connector compatibility.

• No other game abnormalities—only Chunky preloading is affected.

This is usually caused by bad mods in your own modpack. Try finding the minimum set of mods reproducible.

I just tried upgrading the mod Sinytra Connector, and the game didn't respond after the progress bar moved a little

Bro, make issue to Sinytra Connector, it's not a C2ME problem.
