Can someone explain me?

[Radgiox]

I'm playing the mod Invasion and I have a few questions for you:

1. There are some block bugged from the mod WTFs Expedition... is only to me or is like this to everyone?
2. There are some big holes in my world, is that normal as well?
3. I dunno how to sleep ahah... when I click on my bed it sets only the spawn point, how can I sleep?
4. I cannot craft emerald tools apart from the pickaxe, I don't see them in the items list to the right of the inventory... I don't see also other items in the JEI panel but when I change it into NEI panel in the items list appears more items, but I cant craft them as well. Are some items excluded from crafting? With JEI panel I have 11 pages of items, with NEI 13.

3. You can't.
4. Idk
