Checklist

• I am using the official version of the mod.
• I tried the latest development version but the issue persists.
• I searched for similar open issues and could not find an existing bug report on this.

Additional context
I first thought that the problem was in FastQuit, but when I disabled FastQuit the problem persisted, it only got back to normal when I disabled the Concurrent Chunk Management Engine.

[ishland]

Please provide full logs. Also try reproduce without betterchunkloading, smoothchunk, chunksending, limitedchunks.

[rottakore]

Full log provided below:
2023-09-06-1.log

I'll test without betterchunkloading, smoothchunk, chunksending and limitedchunks later and provide results.

[rottakore]

I discovered that the problem is exactly with C2ME and betterchunkloading, I'll provide the log below:
latest2.log

Related to KingContaria/FastQuit#35

[iMoobert]

I have a similar issue where c2me will cause my world to take over a minute to save when quitting the game. This happens even when I join the world then immediately quit after.

I initially thought this was a problem with a mod called FastQuit, however the issue resolved itself when I removed c2me

[xboct02]

I also have these two mods installed and the second one predicts which way the chunks will load, but there were no errors at all.
