@Trife88 : unfortunately it’s not that simple, as the pak system seems to be different in the final release compared to beta 1 to 4. And of course the internal file hierarchy could have changed too, as it did between betas.
Put simply : no way to unpak = no way to use unpaked files as opposed to paked files = no way to override them with custom edits. So from there, no way to even use previous mods until this is figured out. Not to mention that the presence of unpacked files could probably be detected by an anti cheat system I suppose, but that’s another topic of course.
