Thank you very much for digging into that. That's a piece of a Comp. If you right click a Comp it gives you those options. What a Comp from one track is doing in the middle of my Takes for another is beyond me.
Whatever bug I ran into, it had to do with Group Editing, Take Folders, and Comps. I recorded these takes in a long pass then turned on an Editing-only Group and comp'ed it. I have the Fade Tool, Marquee Tool, Quick Swipe and Take Editing click zones enabled. I comp'ed this in a single pass, collapsing/uncollapsing the Take Folder and swiping takes. When using Click Zones it can be easy to split with the Marquee tool unintentionally which I Undo. Those are the only commands I would use. I don't usually have a habit of performing Quick Swipe from the Comp Track itself (on a collapsed take folder) but that's a possibility too.
Well, that's one of my favorite takes. Perhaps I can copy the tracks, flatten and merge the main set, and unpack the copies for safekeeping. After unpacking, if that Comp region is there, I'll delete the overlapping Comp region that doesn't belong.
Thanks again for going through that. It gives me some potential clues for a bug to look out for next time I'm comping a Group.
To tie back to the original thought of Import being crash prone, it looks like in this case it's because it's an "integrity check" of sorts where a mistake Logic made earlier won't import.
