Is it just me, or MVP and Vice MVP no longer receive the Gem Idea Regalia (big one)?

Also, does sometimes it feel like people mess with the game data somehow? Like, I use a makeshift team for level-up, go full auto, come back and see myself as vice MVP even though I did not contribute 1/15 of the damage at all.
...Makes me feel like some people somehow miraculously bring down the Wind Catastrophe, but actually hit less, so their damage wasn't counted by the server.
