I mean, with the feedback from this thread, I don’t know if it’s even the same bug.
Sigh.
I took a look at it. The zombie dog uses the standard zombie harvest, which is tainted meat, fat, bone, and apparently pheromone, though I’ve never seen such a thing.
You could change it to use the ‘zombie_fur’ group instead, (like the zombie wolf) which drops the same stuff but also tainted fur. Alternatively, you could make it ‘zombie_leather’ which would make it drop tainted leather instead.
It looks like this isn’t a cut and dry fix. I’m not sure what they WANT it to have. The fact that it doesn’t drop skin or fur seems like an oversight, but I’m not going to make a change when I don’t know which is appropriate.
