Playable was not disposed warning

I am using instantiate to create a game character and have been doing so for some time. After upgrading to 5.4 I now get this annoying little warning, Playable was not disposed, referring to the line in the code where the character was instanced. The warning shows up after stopping play mode in the editor, but it only happens once, the first time after a fresh start of Unity. If I continually run the project through the same process, no warning. If I restart Unity, I get the warning again the first time it runs through that code.
Am I doing something wrong or is there something I need to set in 5.4 to stop showing this warning?

There was a bug fixed in the Unity 5.4.2p2 patch release that looked similar to this. So I’d recommend trying that version or newer :slight_smile:
