Error while exporting files

[NintwnDude879]

Hi, first post here, not sure if any other information is required but I'm willing to provide anything needed. Right off the bat, error is
FPakFile::Seek64(0x8005E000) - not implemented
and the call stack is
FPakFile::Seek64(0x8005E000) - not implemented FByteBulkData::SerializeData <- FByteBulkData::SerializeData(UObject*) <- UTexture2D::LoadBulkTexture: File=none Mip=1 <- UTexture2D::GetTextureData: LQ_Lightmap_0_231 <- CTextureExportWorker::Setup <- ExportTexture <- ExportMaterial: LightMapTexture2D'LQ_Lightmap_0_231' <- ExportObject: LightMapTexture2D'LQ_Lightmap_0_231' <- ExportObjects <- ExportPackages <- UIMenuItem::HandleCommand <- UIMenu::Popup <- UIBaseDialog::WndProc <- UIBaseDialog::CustomMessageLoop <- UIBaseDialog::ShowDialog: modal=1, title="Choose a package to open" <- CUmodelApp::ShowPackageUI <- Main: umodel_build=1590
Is there any way for me to avoid a call to this function so I don't get this error, or some change I can make to implement this function?
