The list includes "features" (by opposition to "bugs") if they are not documented. To the best of my knowledge, there is no mention of the Sphinx being unable to use the Teleport spell, or of the other immobiles not being able to use Cloud Trapeze (and similar spells). So, I feel this entry should stay in the list (if it is indeed undocumented), but it is indeed not a bug.

Thanks for the information about Magic Duel. About the two "fixed" entries: have they been fixed under 2.16 (or a previous patch for this matter), or will they be fixed by the next patch? I will probably put them at the bottom of the list, in a special "fixed items" list... or remove them altogether (that would depend on whether there is any need of knowing what has been fixed).
