This may have been mentioned already, but it is worth repeating, especially if there is any chance to get the improvement into VV2...
When I open up my villages after being away (work, sleep, or even playing in another village) there may often be a dead skeleton waiting to be buried.
I let my villagers tdo this, even though the graveyard is already full, but occasionally something happens to stop their trek to the cemetary. The GC may throw a party, or the villager may stop and "Wait for someone." In either case the skeleton gets dropped and disappears!
so sad.
Please either:1) code the burials so that once started, they finish without being interrupted by other game triggers
2) leave the skeleton in place to be picked up again later, or by another villager
I would feel much better if my little villagers all got the proper burial they deserved.
