Wand of Polymorph wishing. Correct phrasing?

Hey, all, long time player, first time poster.

Can't seem to wish for the Wand of Polymorph any more? If I type "wand of polymorph" or "Wand of Polymorph" the genie just tells me to be more precise. Same happens if I try something like "wand of polymorph five charges".

Script files don't indicate it's unwishable, so I doubt this is intentional. Is it a bug or am I screwing up the phrasing somehow? If I type (IIRC) "wand polymorph" or "polymorph wand" I just end up with a ring of polymorph. Is it expecting "octiron wand of polymorph", something like that?

A little annoying since I wasted two oil lamps in one game trying to get this.

Oof, sorry. Wishing for "wand of polymorph" should work, there's probably a bug in the wish parser.

Ah, I guess I'll just wish for other things until it's fixed, then.

Maybe there's a wrongly polarised bool check somewhere? A missing or surplus "!" perhaps? That'd explain why the fairly precise "wand of polymorph" gets "be more precise!" while the imprecise "wand polymorph" gets a guess-like delivery of a ring of polymorph. It's like it's skipping a high-similarity data entity and going for the next nearest match.
