Basically I can unpack the Data.pak of this private server but can't repack it. It stops in the middle of the process on a .dds file. I've also edited PackIO in the shadow.txt to 0, the problem still persists.
I'm not exactly new to this and yes, it used to work fine in the past. I'm using the PackManager by Merovingian by the way.
Any help will be appreciated.
