No and I'm really annoyed that I didn't. I don't suppose there's anything I can do about it if it is a glitch?

I did, three times, even left and came back a few hours later but sill nothing. I suppose i couldve been mistaken when i thought i caught it but im fairly positive that it said 'you have caught this pokemon'

I somehow caught a legendary Pokemon against all the odds but I cant find it when I look in all my Pokemon. Is there somewhere else I need to look or has something gone wrong? It was a Dark Tapu Bulu
