Bug - Nested sequences come in too long.
When I nest a sequence, it often comes in significantly longer than the actual run time of that sequence. I get the striped "no media" indicator on the extra dead space.
If I cut it down to the actual run time or shorter, it then recognizes the correct end of the sequence. So I'll usually just tail edit it somewhere in the middle and roll back to the end. This is a strange and unnecessary task to do every time.
