Skeletons not spawning in version 3.2.3

[OMG67]

I'm using forge and the skeletons are not spawning when using the casket, using 128 bones and 2 buckets of milk, 64 leather and 64 beef, placed the gravestone marker and using 2 soil blocks instead of grass (all of this just to make sure it's not me being dumb).

But it still doesn't summon anything when using time set midnight.

Just to confirm, are you playing with just Overlord or in a modpack? If you're in a modpack, have you checked the recipe in REI to see if they changed it?

[OMG67]

I'm playing it on a modpack made by myself, worked until I updated the mod, I've made no modification to the mod yet.

What version did you update from?

And what Minecraft version?

[OMG67]

I updated from the last update before this one, so I'm guessing 3.2.2 MC version is 1.18.2 forge

Fixed in Fireplace Lib 7.1.0
