Link messages overwite current line in session rather than appending

**Describe the bug**

When I make Link report actions to the session by setting the appropriate flag it's printing stuff like this to the session:

```
Link @ 07:59: #.Namespace.Objectwritten to C:/...
```

That's fine as such, but it does not append the message to the session, it overwrites the current line. I think it should not.

(This is my <01978>)
