This is an incredibly annoying thing about Face Robot. It’s caused by saving a scene with Face Robot enabled. You can go on to infect other scenes with FaceRobot if you have it turned on causing a big headache for yourself.
There are a number of solutions but the best one is:
- Open your scene and go to the Face Robot toolbar at the top of the screen. On the dropdown click Disable Face Robot. Then go to your explorer and delete the Face model and the ActiveFaceRobot data map. The re-save the scene over the one you just opened.
Make sure you have good Face Robot hygiene, re-save over all affected scenes and this problem should not occur again (that is unless, you actually want to use Face Robot).
Edit: Whoops, I see you have already sorted this problem. Well the information is there for anyone else.
