The BedGlobals code is way too fucked up for there to be a legit "their" side. The issue is moot. This whole ownership issue should be handled with Inge-style ownership.
Sorry, I wasn't clear. I am clearly not awesome. I don't mean anything the game handles. I mean when I send them to bed I click one side of the bed for one of them, and the other for the other. Before, they went to the side I clicked on. Now, with this hack, they do again. It's a minor thing, I know, but it was annoying me.
