Hm. Mine was a completely fresh 1.02 install + your patch (Nov. 25 edition) correctly installed (version "A," deleted the 000.dat), with no old saves existing whatsoever. My wife hadn't learned Gecko skinning yet (hadn't even touched the Smiley chain, she says), but had found a few pelts in a crate at Trapper Town in Klamath.
I'll test it myself now, will edit in results.
Edit: Yeah. In Klamath, setting down a Golden Gecko pelt leaves the dead Golden Gecko on the ground, but setting down a regular Gecko Pelt leaves a cardboard box. I'm only in Klamath, so I couldn't tell you about Fire Gecko pelts yet.
Edit II: Er... now both pelts (Golden and regular) are showing as cardboard boxes. I definitely saw her dropping and picking up the dead Golden Gecko model last night, though.
