Here are some more photos. One is of the staff of assistants and he isn't listed. Another is of the he objective asking to get him to level 15. And there should be another photo of a search for staff with his name. And he is not popping up.
Any other information, please let me know and I will do my best to get that for you. Appreciate your assistance. Apologies for the delayed response.
I had Winston Wailon in my museum at one time. But now I cannot locate him and he is needed for a POI Type Staff XP to get him to Rank 15.
