qwk errors / libarchive

Hi i'm setup my sbbs as qwk network hub

I found two issues:

  1. A mystic node that connect to my system to get the packet, get a libarchive error when making the qwk file at sbbs log

Jun  9 00:23:52 scarlet synchronet: evnt packQWK <DCKMYS> Packing completed: /sbbs/data/file/0195.qwk

Also te mystic log show a invalid zip file error when process it:

Although these errors exist, messages seem to arrive from one system to another But I'm not completely sure if everything is okay. thanks!
