Auto-close not applied to moved topics (possible regression)

I am getting some odd behaviour on moving topics into categories with auto-close (first reported here).

Here’s some of what I did:

  • I moved a topic with over 100 replies to an auto-close cat, but auto-close did not get applied.
  • Also added a slow mode to the cat, then created a new topic and 1 minute later moved it there - both autoclose and slow mode were applied.
  • Moved the other topic (the one with over 100 replies) back to its original cat, then back to this auto-close cat - but only the slow mode was applied.

Not sure what’s going on here but if you need me to test anything just let me know.
