Issue-

I put a chunk loader on a powered create clock module (the clock mechanism with sticky rotational front) on the minutes hand for continual uploading.

After first log out, the world is bricked and will not load.

The chunk loader is in continuous entity form, as part of the clock module. I'm fairly sure this broke the world.

Was survival playthrough with many hours, please 2 fix <3

Additional info-

No other modded blocks used, oak planks for hour hand, nether brick wall for minute hand, chunk loader attached to wall with glue at top of wall.

Tried uninstalling chunk loader mod, world is still bricked.

Do you have a log from when this happened? Is it reproducible if you try it in a new world?

I'm closing this as it's not actionable in its current state. If you are able to provide more information, let me know and I'll reopen the issue.
