Hello there. I cannot create a own topic so I post my questions here. I have questions about editing the vanilla campaigns of OA and BAF in the editor. Therefore I learned I have to unpack the *.pbo files so I can load them in the editor. But where is the file containing the campaign missions found and how is it named? Furthermore I cannot extract the missions_baf.pbo file in the Baf/AddOns folder, the pbo-Tool refuses to unpack the files. Can anybody help?
