Import session data flakiness

I've recently been importing old sessions into new ones (for revisions) and found Protools reporting missing files. When you tell it to find them it can't. Now when it's done trying to find them and the session finally opens the timeline shows as complete (green) but the session shows red (missing something). If I look in the regions list there is nothing greyed out to indicate missing files (thus nothing to delete to get a green light on the session). In the Task window it shows the missing files it wasn't able to find and they are actually FADE files (I'm assuming this is why they aren't showing up in the regions list). Theses fades (that Protools thinks are files) still show up as missing if I check the regenerate missing fades option in the missing files window.
Anyone else experience this behavior?
