There were no crashes, force quitting, editing files or anything like that. I was pushing the game hard though, and getting errors about carrying too many items as I tried to load myself and the cows.
Thanks. I'll check it out today, and e-mail you back.
EDIT: I suspect the leash duplicates may have occurred when I was already carrying the maximum number of items and then I took the leashes from the tree I had tied them to. If this pushed me over the item carry limit, I may have dropped some stuff resulting in the leashes getting duplicated?
It's likely that the (internal) item handling difficulties was a cause of the issue, but it's not possible to confirm it 100%.
Nevertheless it's something that we don't want to happen, so we'll see about the possible adjustments we can do.
EDIT 2: I would appreciate it if you could confirm that a defeated Njerp village can flip to Vagabond, erasing the Njerp buildings and presumably my cattle if they were tied to a tree within the area. I just need to know whether I can expect to chew the cud with my beloved Ermintrude ever again, or if I should plan a mission to secure some replacements!
If all the villagers are dead, or just leave the village, that cultural area turns into no man's land and the villages at no man's land are called vagabond villages.
So for that part it can happen and works as intended. BUT buildings in the defeated/abandoned should never be erased nor replaced - so that sound like a bug.
