First off, I use a variety of hardware, and none of them have anything to do with this particular bug, as I discovered it in offline mode.

I'm a radio DJ, and I use my Serato crates to sort my song categories. I have my master "rotations" crate, with several subcrates within it. A, B, C, etc. are my categories, and then I have 900, 930, 1000, 1030, etc. for my time slots. My process is that I'll drag tracks from from the categories crate into the time slot crates before I record my mix show segments, and the then the following week I'll delete all songs within the time slot crates and so that I can create new set lists for the current week. When I do that, the tracks are then removed from ALL crates within the master crate, not just the one time slot crate, as has always been the case.

This started happening in 1.8, but now it's happening in 1.78 as well. Anyone else experience this? I'm on OSX 10.10.2, Retina, i7, 16gb, 500gb SSD...
