I'm having the same issue, with the same error. Even tried using older releases and same thing happens. Using Minecraft version 1.20.2

Same

froggygroggy commented 1 year ago

ive been having this problem for a while, please let me know if you find a fix! ive tried everything. it works for me in older versions of minecraft but unfortunately the server i want to save my world from is only 1.20.

febrance commented 1 year ago

Guys, Minecrafts Server protocol (Especially the chunk protocol) was modified in 1.20.2. You can use 1.20 and 1.20.1 no problems but 1.20.2 has some optimizations for low bandwidth machines, it will now send the chunks in small batches and not a huge batch of chunk data. Thats why this Tool cant read new 1.20.2 Packets properly and gets this out of bounds error.
