Moving track in project window makes it disappear

Hi, I just switched from cubase 12 to cubase 14 (yes, 14, not 15 - I’m conservative and try to use only versions that are there for long). I noticed what seems to me a bug:

I’m in the project window - I split it using the “divide track list”.

Then, I’m selecting a track from the lower part and drag it to the upper part (that already contains tracks). If I “release” the drag anywhere between the existing (upper part) tracks, then the track I dragged moved perfectly. If, however, I release it at the position that is lower to the lowest track in the upper part (i.e., the “last” track in the upper track) then the track kind of disappears… It didn’t fully disapper, as it appeared in a pretty random place in the bottom part. I am adding some screenshots to demonstrate it:

SCREENSHOT1: “Before” picture: Well this is where I start. Please have a look at a track called #hdj2 (that has a “track number” of 8).

SCREENSHOT2: “Proper behavior”: I now drag and dropped it to the upper part, just above the last track. It “made it” and appears with track number of 5. So far so good.

SCREENSHOT3: I did an undo and brought myself to what you saw in screenshot 1. Now I dragged and dropped it BELOW the last track of the upper part (i.e., below “gg TMBK”). As a result, it simply disappeared (!?) - wait, go to the next screenshot (4) to see where this track is displayed… BTW, if you may have noticed, the track numbering for the upper part became strange - there is no longer track #1

SCREENSHOT4: Well, our poor track survived. It appears in a pretty random area towards the end of the project - and with track # 1 (!!??)

This is clearly a bug, and a nasty one (as the track disappears and randomly appears elsewhere). In the past I received a response from steinberg on such reporting. I hope this was not overlooked just because I sent it over a weekend…

Yep been happening here since Cubase 13. Manifests in large sessions. Can’t reproduce but I suspect it has to do with using the “upper divider.”

You’ll also find that if you export the tracks they don’t export with the proper numbers anymore, so there’s clearly some kind of numbering bug happening internally.

Hope you can reproduce it for us!

I can reproduce at any moment

I too can reproduce in any moment in a session once it becomes problematic, but can you list a series of steps for tech support or another user to replicate it?

Well, I will try tomorrow. I suspect my description (that used the track divider + drag and drop to below the lowed track in the upper part of the screen) will create the same issue even in an empty project that has very few empty tracks. If I’m right then we have a bingo. If not, I can send them my project, or a sanitized version of my project (unless you already did that)

Unfortunately, I cannot recreate that in a new project…
