I was sitting with my mule at a depot and the person next to me had a mule too. When he said "follow me" his mule followed him and mine disappeared altogether. I had to go get another one from the mule-giver-outer and I had to pay another 2.5 silver. My things were still inside, but I got cheated out of 2 silver. Has this happened to anyone else, that someone stole their mule (on accident, Orteg :D) as well as their own?
It is a known bug, you didn't lose two silver, you get that back when you return the mule. You lost 50 copper for rent. Your things should still be on it.
