An incomprehensible error when I break blocks

[powerbute]

The server made a lot of requests during the blocks breakage, both clients got stuck, the frontend crashed after a short time.

Thank you for your submission.

It's interesting, I haven't encountered anything like that myself.
It looks that that you're really far in the overworld. But there are also logs that indicate that you're on normal chunks.
From the screenshot I can see that you've walked into a broken chunk which might have caused the issue. And yes I'm aware that
there are chunks that client doesn't seem to accept for some reason. And there are tones of issues when you try to interact with these chunks. I'm hoping to fix those soon
