@Big Beak The add-ons are working again, but I’ve still lost everything in my world that came from an add-on. Hours of work I’m going to have to do all over again.
Okay, I've added a couple of videos. The first I was using optifine so I did it again completely vanilla.
Ah, cool. I did a search for nether trees but nothing came up so I thought it wasn’t reported. They worded it differently there, and I see that there’s more to it than I thought as well.
Well, just looked it up, and you're right, I've just never seen that happen before. Never woken up with an Enderman in my house.
They can't teleport inside a building they can't otherwise get into.
There's no way an Enderman could have gotten into my base, and where would they get a grass block or Sand Block from in a stronghold?
When the items are generated, they do briefly exist within the block, and then pop out of it. Shouldn’t the behaviour of the bee nest work like a container or composter and if there is a hopper under the bee nest, all items that come out of it, whether from dispensers or a player using shears, be picked up by that hopper?
