Thanks for reporting this! Are you dropping in some special kind of target? Or are you just grabbing and dropping the morph to a different position in the world?

Just in the world

After watching the video some more, I think what happened here is that somehow the system tried dropping the morph inside of the Halo's tooltip at first, which messes up some state. I could not even grab a morph with a second tooltip still being visible on the current main. I'll close this for now and reopen if the problem should arise anew.
