Yes those were the Issues and were considered Harassment / griefing (The loading up the stable).
Yes Runebooks were not blessed originally (but were before I left).
Yes you died you stood the chance to lose your pet army, IF you were carry them around in your backpack.
The one thread I did find (on a free shard) states it mostly as I remember that if someone ever did click the statue, the pet would be restored to you. As I said, I have never played a Free shard.
I can remember Fire (A Red Dragon), Ice (A Pure White Wyrm), Night ( A Nightmare) and the Vet Reward (A Desert Ostard) all setting in a pack (plus the tameds I considered disposable) in my house.
I can remember going to a desired spot, mark a temporary rune, recall home, get the pet of choice and recall back, make pet alive. When done, make pet a statue, recall home, put it back in the bag. I can also remember turning the pet into a statue when the fight was a lost cause, hiding and restart the engagement. Which probably was an unintended consequence.
Most of this isnt trying to dismiss what people are saying, it is trying to reconcile the UO I am playing today vs the One I left (Why on earth did they remove the ability to transfer pets to lower level tamers?).
