NAO forgets learned faces randomly

[Patrick18051992]

When using the OpenRoberta Lab and the humanoid robot NAO there are issues when detecting faces. The openroberta lab sometimes forgets / deletes a face from the robot's memory without the user excplicitly telling the program to.

Steps to reproduce the behavior:

• Create an application for NAO
• Make NAO learn the face
• Make NAO recognize the face
• Run a new programm to just detect the face (repeat this action several times, sometimes the face will still be learned sometimes not. I was connected to NAO and monitored the events, at one point the list with learnt faces was emptied)

Expected behavior
NAO remebers the faces until the user explicitly says forget name or faces are always deleted from memory after an application stops (what doesnt make much sense)
