Maxameleon didn't disappear

When I started a new game, the film projector sound kept playing when the gameplay started, so I save/quit right away and went back in to see if that would fix it. It did, but it also seemed to make Maxameleon forget to disappear, because he just kept sitting there forever, able to be examined. But I did a save/quit right at the start of the game other times and it didn't make him forget to disappear, so I don't know exactly what triggers it. It's day six in the screenshot I took, so you can see that he's still there after many in-game days, when I believe he's supposed to disappear immediately upon the start of a new game after he makes his snarky comment about your ballooning skills.
