Since there are mines near Krofburg and lots of miners going back and forth to the city, it seems there should be goats available from an NPC farmer around the vineyards right? It would make things more consistent and convenient. Don't know if the ox scripts could be easily duplicated with lower carrying capacity for goats, but that would be really handy. Animal handler Blarney's recent presence in Krofburg could even explain goats being tamer perhaps. Providing oxen somewhere would be good too I suppose, but goats just seem more regionally appropriate.
