I don’t know why I can’t make a topic in a certain category (Features) today as the “500 Error” message keeps showing up. I did make a topic and forgot to move it to features, when I moved this, The message keeps showing up

There is a nasty error in Active Record, where adding a `#includes` on a model can cause various queries to explode when we pluck ids.
`op_likes` ordering (order by number of likes on first post) was a pretty hidden feature only exposed via the default category order dialog.
We are pulling the feature altogether, @techAPJ will pull it and add a migration that remaps this to order by likes for categories that want to specify it as ordering.
In the meantime @techAPJ changed the offending category on infinite flight to order by likes by default.

Actually looks like this is a legit bug in our monkey patch, so I went ahead and fixed the monkey patch, per:

I reverted my change on `community.infinite-flight.com/c/features` just now to sort by Original Posts Lkes and can confirm that everything is good now. 👍
