My Elephant and Trader Llama were accidentally attacked by a Mutant Enderman, and tried to retaliate. They sadly lost the fight, and both died. Thankfully, they both have Pet Beds. My Trader Llama respawned like normal, but my Elephant has been acting strangely. All it does is sit in place. I can still ride it and access its chest, but it does not move. I can also still feed it Apples, Acacia Blossoms, and Saplings manually, but it does not eat them off the ground like normal elephants do. Is there anything that I can do, or is my elephant now just a glorified chest?

I found the fix for this. My elephant was in "sit" mode when it respawned, and I was able to make it move again with the command drum. However, I still doubt that this is an intended feature if Elephants cannot be told to sit without the drum.
