Description of the bug

After I tried to convert a folder into .vpk file, bee2 break every export, or even uninstall systems.

Expected behavior

root would convert into the root.vpk file.

Steps to reproduce

Step 1: put any folder into the vpk_override folder
Step 2: export anything to Portal 2
Step 3: MultiError: error('unpack requires a buffer of 18 bytes')

Additional information:

I cant ever verify game files after this happened. 
Btw BEE2 was the best way to make Portal2 maps, devs did their work very well.

Try deleting portal2_dlc3/pak01_dir.vpk, it sounds like that got corrupted.
