Hi All,

I brought 2 boxes inside the mine and filled them with ores, since i can only carry one box at a time i left the remaining box with the lid closed. Once i have loaded my initial box loaded with ore into my horse cart, i returned to the mine just to discover that my box full of ore was missing.

I searched inside but its nowhere to be found. Is this a bug? or the boxes will just respawn? if it will respawn, where can i find it? 

Thanks in advance!

I think that anything left in the mine disappears when you walk out since it loads the outside area upon walking out I think. The box was probably reset back to your house and the ore is just gone.
