After T222024, I want to cleanup pages that title starts with Appendix and in main namespace. So I move those pages by API (specify fromid). [[ https://zh.wiktionary.org/w/index.php?title=Special:%E6%97%A5%E5%BF%97/move&offset=20190529140000&limit=2&type=move&user= | 2 pages ]] is ok. But 1 throws
```
