I get it its upsetting to lose a thrall but on the off chance they did this on purpose then it makes sense. Why should thralls be immune to fall damage when everything else is not? Kinda weird no?

Having said that now that you all know this happens, build smarter and watch your thralls more carefully.

All this can be avoided for now until they either ‘fix’ it if its an actual bug or not
