Ok I need someone else to test this bug to confirm it but here's how I accidently produced it.

I birthed a meeroo from a nest and set it to market mode. I had moved the meeroo over to my friend's lot to avoid having it attaching to any of my stumps.

After some time had passed the meeroo managed to get on my friend's stump! Instead of finding one of mine to hop to.

Now note.. meeroos in market mode take a while to find a stump to attach to. So it might not happen right away.

Try it and come back 10mins to see if to works.
