I think that would solve the problem of many.
What happened is that the jar of thralls where i put the food is pointing out that a thrall still alive, but i can’t find it and i have already been to the last places i was with him, the event log says the thrall came home, but it is not what happened.
I think this is the bug that is happening.
A sniffing animal would be useful because what happened to me was when i died, the thrall was to appear far away from the place where i died. I thought i lost it, but i found it 2 days later while exploring.
It’s a little stressful, it takes time to find a good thrall, it takes a long time for him to level up and suddenly the game makes the biblical rapture in the thrall
