When I try to move the milk bucket in my hotbar, if it is selected the milk disappears as soon as I click on it. If I select another hotbar item and then open my inventory and try to move the milk, I am able to.

I built a bridge out of spruce wood blocks and they won't show up on Pre-5, but they did on pre-4. Also, Dark Oak slabs don't seem to show up. I made a map of a Woodland Mansion and you can't see the roof, just the interior rooms.

Thanks for the explanation, you worded it a lot better than I did. I wasn't sure what the problem really was, just that it was a change in observer mechanics. That makes a lot of sense to me.

Can confirm - I had a pigman farm and the pigmen would get stuck on the new trapdoors and not fall down. Replacing the new trapdoors with original oak trapdoors solved the problem.

I have the same issue - 1.13-pre5 and /locate Stronghold returns 8 ~ 8 for me as well, no stronghold to be found.
