Index out of range error in buffer.js caused by A* callback #25

This is an error that randomly occured while my bot was walking around the world (in Nether):

  buffer.js:506
      throw new RangeError('index out of range');
      ^
  RangeError: index out of range
      at checkOffset (buffer.js:506:11)

Probably it's checking non-existent blocks or something like that. I don't know how to fix it :(

I got the same problem while parsing a binary file with ~12Mx28B records . Any help?

I don't think these errors are necessarily connected. Index out of range can mean anything.
