I’am having the same problem for almost half of year.
Didn’t helped the methods above, but I have one method, that works for me with 5% probability ? In AME when I see red card with “Media Offline” I click stop, then choose other Renderer (I’ve got 2), then Reset Status on sequence, then hit play again. On this step I have 5% probability to render my sequence with no media offline, but with normal online media.
But that absolutely is not the solution. So I’m looking for the right solution of this problem! Please, help.
