Comment (by eriktorbjorn):

 If I understand correctly, object state 0 means drawing is suppressed.

 The problem with the appearing/disappearing stairs seems to have something
 to do with it triggering a call to `drawRoomObjects()` while the twisted
 stairs are still visible. It draws objects 554, 553, 552, 551, 549, and
 547 in that order. The last of those is, of course, the part of the stairs
 that should not be visible at this point, but its state isn't zeroed until
 afterwards.

 In a subsequent call to `drawRoomObjects()`, it only draws objects 554,
 553, 552, and 551.
