Expected Behavior

No exceptions in log

Steps To Reproduce

Not sure, happens seemingly random.

Edit by Lucas:
Happens when an entity steps on a pressure plate.
The state of the pressure plate seems to be null, or the block data is null. Not sure if it happens randomly.

Can you try to reproduce this on a clean PaperSpigot server?

[Sculas]

Seems like it tries to get the block data of a block that doesn't exist.
...
...what?

[Sneakometer]

Can you try to reproduce this on a clean PaperSpigot server?

Not sure how. I don't even know what causes it.
I opened the issue in the hopes someone knows what could cause it or point me in the right direction.

[Sculas]

The only way to know what's wrong is by looking at the code, sadly I cannot do that right now. So if someone else wants to look, feel free.

Just found a new variant of this error:

Do your plugins do anything related to Item/Firework/Arrow entities? If so then they may be causing the issue.

[HowardZHY]

I remember this could happen on Taco and TorchSpigot , when a zombie or skeleton bumped into cactus and got damaged , there's an error like this.

Only thing that i could think of is some semi illegal asynchronous api usage (read only) in our anticheat.
I'm gonna test if the issue persists without the AC.

[crafter23456]

I couldnt reproduce it on latest build 706108e with multiversecore.
I dropped zombies + items on diverse pressure plates and cactus. Nothing in log.
Probably wanna try if it still happens @Sneakometer
