Hello Pop,

Just update to the most recent paper 1.16.1 (Paper 137) along with just updated Chunky to 1.1.3 and started to get this error every time it generated a chunk.
Below is the pastebin!

That's actually an issue in vanilla with updating from 1.15 to 1.16. Please check out MC-191388 for details about this bug.

Oh by the way, you can either generate a new world on 1.16, or you can just ignore the spam (should be mostly harmless, IIRC some grass in villages might be missing but that's about it).

Thank you Pop! I guess I should look a little more into the bug before I report it. I always forget the Mojang has their own report site that you can look up bugs on. I guess I should always check their first to see if its a Vanilla problem.

Mojang just wants to make everything hard on you Developers dont they :)

No problem! Also I find it hilarious that you are finding all these errors, usually everything just works. 😛

I pay attention to my console every time I start the server. I am one of those Developers that likes to look at what is throwing errors. Most of the time it states that the Developers of the plugin already know the issue and they cant fix it because their plugin relies on the function.

Yeah, makes sense. For the most part, Chunky just assumes that there won't be any critical errors during chunk generation. If there are, the task will fail. In testing though, I have had tasks running for days straight without any issues. So in practice, nothing bad should really happen. 😄
