I don't know if anybody else is experiencing these issues but, the following files in this pack seem to be corrupted and cause the game to either crash or have the menu glitch out.
pac\menu\win\Assets\wwe19_texture
Itag_cas_win.pac - glitched menu in creation suite
Itag_common_win.pac - causes the game to crash when exiting from matches
pac\menu\win\Assets\wwe19_anime
Itag_loading_general_win.pac - causes the game to crash when loading into show intros & when hitting continue after a show is completed in universe mode
This can be fixed by replace these files with the original and it seems to have no difference on the menu mod except that when loading out of universe mode the normal wwe logo shows.
The files from the dark mode can be used for the creation suite files to give it a matching look.
