In the Twilight Forest it is always night.
So is not possible for a vampire to put his spawn point.
The coffin always says: "You can only sleep at day".

Reproduce Steps

Place a coffin in Twilightforest or another dimension where it is always night and test to sleep.

Additional Information

I am a big French fan.
Thank you for your work.

I will think about his, I guess I will change the coffin to set the spawn point earlier (before checking for daytime)
