Re: [Gameplay] flipping defense busts the defensive coverage
@Ship08 Are you talking about H2H or Solo modes? I think there is a setting to switch "auto flip" off but I'm not sure how it exactly works (i.e. whether it is only in H2H or Solos, or after selecting a play vs. after an audible).
I get busted in H2H sometimes when I use Man Coverage and my opponent sends a guy in motion. For some Zone Coverages, the issue might be there too, depending on how the players are lined up.
I've also reported a glitch in Solos where the AI goalline defense can often be easily beaten just by flipping the play. Therefore I'd agree that this is an issue.
I've moved your thread to the bug reports section. From my perspective it is clearly a bug.
