Can we repro this @techapj?

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:
