Zip extraction failure when reobfuscating

[moderatorman]

Beta 1.7.3, OpenJDK 1.8.0_312. Error occurred while running reobfuscate.sh on Linux Mint, all updates applied. I'm not sure if this has an easy fix or not, but any help would be greatly appreciated.

I can see that it has something to do with zip extraction and a missing class file. But I checked, and I'm fairly certain it's where it should be.

Edit: Full mcp.log here & mcperr.log here. Traceback below.

Try to run updatemd5.sh before reobfuscate.sh
