Crash: "java.lang.IllegalStateException: POI never registered at eu" when opening certain block entities

This POI illegal state crash also happens with entities, see MC-145686 (EDIT: fixed referring to wrong bug...).

Just adding my voice to the mix,  yeah I get a crash trying to access my barrel I have for storage in a house I built

Can confirm, barrels have become inaccessible, but chests seem to work strangely, although I cannot confirm that they were placed in 19w08a.

Can confirm, with this crash happening every few seconds or so on a map loading 80 villagers, and involving ticking hoppers.

Creating a fresh new world in 19w11a, finding a villager and firing TNT near him also crashes the game. In my case there were no relation to previous versions of the game.

I had this crash while a villager was on fire after being set on fire with lava. The crash report in this instance has a different stack trace.

@unknown, that's MC-145756.

Still happening on 19w11b while accessing a blast furnace

This bug is unchanged for me between 19w11a and 19w11b,  both the same items are ticking and it affects all not just one in one location.  Ticking only occurs when attempting to open the barrel. An opened barrel remains open ticking, destroying it ends the crash cycle.

Details:
Name: minecraft:barrel // brt
Block: Block{minecraft:barrel}

Still the same in 19w11b. No changes.

The bug seems to be fixed for me, however I went from the 19w9a snapshot directly to the 19w11b snapshot. For those who are still having the problem, did you go from 19w11a to 19w11b, or from an older snapshot?

Then I shan't even bother downloading the latest patch then until it is really fixed.....  Darn, I really need into my barrels.....

Now I can open barrels without crashing.

R Gravel, I wouldn't even bother trying!!!

You can't tell if a glitch is fixed if you don't check it first.

It's fixed for me.

Try it!

I was having this issue with my brewing stands (MC-145858) in 19w11a.  It's still happening with 19w11b.

I can confirm this is fixed on my end, looks like there's multiple problems here

Upgraded from 19w09a as 19w11a was not usable for us due to the previously placed barrels crashing us. Now updated to 19w11b and it seemed to be fine at first (at least one barrel placed previously worked) but then it still crashed with the same error at one point, player reports he opened a barrel.
