Describe the bug

When I disable fatigue side effects, I can't sleep.

Is this bug related to another mod?

No.

Steps to reproduce

1.Change the config.
2.Start the game, the value of fatigue displayed on the interface is 0.
3.When I right click on the bed, it works normally.
4.When I right click on the bed for the second time, the value of fatigue displayed on the interface is NaN, a message appears with the content of "You're not tired yet".

Expected Behavior

I hope that the rules related to fatigue can be prohibited while keeping other rules.

Additional context

Here is the link of my config.

I was able to fix the issue, sleep should work fine now without fatigue building up.
Also timings.validSleepEnd appears to be broken in your config, preventing acceleration from starting at all. Setting it back to 24000 will do the trick.
