Contents of dump_pe.txt:

Binary world version: '\x08'; compressor: (4, 2)
Binary world version: '\x08'; compressor: (4,)
Binary world version: '\x08'; compressor: (2,)

How to reproduce:

I installed MCEdit-Unified from source and followed the instructions to copy the _nbt.so into place from the last binary distribution.

I exported my world from the Windows 10 version of Minecraft, copied the .mcworld file over to my Mac (since that's where my development stuff is), and attempted to load the file.

I don't mind uploading the world somewhere if needed, but it's 86MB.

See if you can reproduce this on a smaller world and send that. It might just be that we need to update the leveldb.dll

MCEdit 1.5 is not compatible with Bedrock worlds. This is a different issue

[servel333]

I thought the whole thing with unified was that it was compatible... Am I missing something?

[gentlegiantJGC]

MCEdit 1.6 is but 1.5 was released before Bedrock existed

[servel333]

I see on the website that 1.5 is the latest. Is there a release for 1.6 somewhere else, or is it unreleased?

[gentlegiantJGC]

It is a beta on the website. Bottom right of the top box

[servel333]

It took a minute, but I see the download for MCEdit-Unified 1.6.0.53-testing.

Thanks for the help!

[servel333]

That worked. It looks like it doesn't support some of the new blocks, but it is working and that's what I needed. Thanks again.
