FLinkerLoad::VerifyImport()
contains the following line:
TokenizedMessage->AddToken(FTextToken::Create(FText::Format(LOCTEXT("ImportFailure", " : Failed import for {ImportClass}"), FText::FromName(GetImportClassName(ImportIndex)))));
Which leads to the following warning in the log:
LogText:Warning: Failed to parse argument "ImportClass" as a number (using "0" as a fallback). Please check your format string for errors: ": Failed import for {ImportClass}".
Suggested fix:
replace {ImportClass}
with {0}
, or fix the text formatting to really support named parameters.
Cheers,
