Last edited bar lost after saving and reopening project

Having trouble with LMMS? Ask about it here.
It's not always but some projects I worked on has this issue.
The last bar I edited on the song editer, after I saved my project and next time open it, just went lost.
Not sure if this is a bug (and someone else has already reported it), I don't have a Github account so I just post it here. :)

Yes. There are issues in our GitHub tracker that describe disappearing elements.
Does this one fit the description? https://github.com/LMMS/lmms/issues/3964

Yes, and the fake/real block issue, I've experienced it a few times too.

OS: Windows 8.1 with Bing

As in happened every time?
Do you have a project which you can replicate this with?

Hmm but yours are different. You clearly said "The last 'bar' i worked on"
The known "disappearing-segment" is a post-copy event, but you have a missing last (?) bar OR segment
That is important!
A missing bar would be loss of the last part of a segment
A missing segment would be loss of a whole part of song-editor content
We call these for Segments:

If we look at the top, that track has 4 segments
Three segments are 2 BARS long
One is 7 BARS long
So you can see that there is a significant difference between segment and bar
Therefore we need to know:
Have you lost the last
* BAR of notes?
* Segment of your track?

There is of cause still one risk of misunderstanding.. If your last segment only was one bar long, and it is now missing, then the empty block would still be visible in song-editor, if you only lost a bar of notes, but it will be completely gone, if you lost the segment.
That would look like this

@zonk -Obs its 32x So was mine originally -I have not seen this happen since i got 64x

Thanks for the explanation! :D
I'm pretty sure it was the last segment, more than one bar long and containing multiple notes, that went lost when I reopened the project.
The strange thing is it happened two times yesterday, but since then no more. (today works well)
