BTW... your audio is still there and accessible (if you didn't coompletely cover up the underlying clip). You just need to slip edit the ends to restore the clip(s).
 
Open Lanes to do this.

The audio is still there but and it is accumulated in a selected clip I am moving and erased from the tracks that were on the way. I am sure it must be a bug,  I cannot find and practical use for a such clip behaviour.

Does it look like this?

Because if it's doing that weird "magnetic" type action I have no idea and that does look like a bug (that user is still on X3 I think).
 
However if not I still don't quite understand what you are doing. Like I said if you drop clips onto other clips in the parent track or do it in the same lane then in certain scenarios it will gobble the underlying clip.
 
When I'm doing things like that I do it with Lanes open and it's not a problem.

When you say "accumulated in a selected clip" do you mean that where two (or more) clips existed, now only one does?  The new clip is a combination of the two? 
 
Sorry if I seem dense, but I'm trying to understand your problem more clearly.

Perhaps its my bad english.
 
 The clip I am nudging (left, right, track up, track down) "swallows" the content of the clips that happen to be on the way. New lanes are created inside nudged clip. Imagine your project is a grass field: the selected clip works like lawn mover when nudged. Say I want to move a clip down from track 10 to 13, I press nudge down three times and this clip takes with him all the audio it touched from tracks 11 and 12. Now this clip has two extra lanes.  Lets say in track 13, between this point and the end of song I have several audio clips. Then I nudge the clip to the right in track 13 until end of song. It will take all the audio of track 13 to the end of song, creating even more take lanes. It has never been like that before, it slows me down so much. Oddly on other projects I have no problem.

I know exactly what you mean. I've seen it too. Nudging a clip does a pacman job on other clips that it passes through. This only seems to happen with clips that have been created in take lanes, but still occurs when the same clips are moved to a new track.

I've never bothered to report this bug, as I assumed that it must have already been fixed. I've never seen it mentioned by any users of the current version of Sonar (until now). I'm using Sonar X3.

My copy/paste settings are "replace old with new" so that my be the link to the behavior. There is another thread with "blend old with new" which absorbs the other clip and makes the wave form grow. In my case it wipes data from the track it passes over like in this post.
 
It only appears to manifest itself when take lanes are expanded for me.

Oh... wait. We're talking about nudging through the existing clips? Well... yeah. That's why. Nudging is like moving and dropping a clip in increments so that behavior I mentioned before where if you drop a clip on top of an existing it will "eat it" applies in this scneario.
 
Create new lanes if you intend to do this and put the clips that are to be nudged past other material into those new empty lanes.
 
Yet another reason I prefer to have only one clip per lane even when there is no overlap.

No, this "pacman" behaviour only occurs when using the Nudge facilty, not when dragging clips using the mouse.

Perhaps I have found a workaround to the problem. I saved the project as Cakewalk Bundle and so far nudging clips goes as it should.
