> Console output: Why are you thinking there is a post without topic? I didn’t read anything like that? Why is the rake task saying the first method „acting\_user“ is undefined?

It’s [failing to set the topic’s `acting_user`](https://github.com/discourse/discourse/blob/master/lib/post_revisor.rb#L132) because `@topic` is `nil`.

You could try the following [Data Explorer](https://meta.discourse.org/t/32566?silent=true) query to find the problematic posts.

```sql
SELECT *
FROM posts
WHERE NOT EXISTS(
    SELECT 1
    FROM topics
    WHERE posts.topic_id = topics.id
)

```

Anyway, I [changed the rake task to continue remapping](https://github.com/discourse/discourse/commit/81427e26ea7563c6a43148311130dfe5eccc9b17) when an error occurs.
