Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
1. Having Lioden up in two tabs - one on the lion being moved, the other swapping accounts. 1st screen shot shows lion from main viewed by alt.
2. Once the account swaps to alt, I'm still able to move caves on the main account. 2nd & 3rd screenshots show updating the lion and it being successful.
3. The lion does not move to the cave specified since it's on the wrong account, but if I switch back to the main account I also can't locate the lion, since the cave is unlisted. 4th screen shot show the lack of cave. I went back in my browser history to locate the lion.
