/script unit gender macro

Did Blizzard change the code to display a target's sex?

I use the following macro to display in raid/party chat whenever I Polymorph a target, and not display if I'm solo.

/script if UnitSex("target")==1 then g="F " else g="M "end;s="Turtle "..g..UnitLevel("target").." %T";a=0;if GetPartyMember(1) then c="party" a=1 if GetNumRaidMembers()>0 then c="raid" end;end;if a>0 then SendChatMessage(s,c) end;
/cast Polymorph: Turtle

Recently, I've been seeing bosses show up as F (female) whenever I try to sheep them for fun to see what sex they are.

However, today on Patchwerk I decided to do it again, and he showed up as female, also. Somehing seemed strange, so I tried the macro on my female party memebers. No mater what targt I had in my raid, whether a male or a female, the macro came up as:

Turtle M 60 Soandso

Patchwerk came up as

Turtle F -1 Patchwerk

Did Blizzard change their coding to aquire a target's sex?

Please help. Thanks.
