Ignored tempo change
The tempo change in bar 39 is ignored.
Quite curious, but it seems similar to the old problem Odd pitch bending problem

Just spotted your post by chance, and not knowing the exact reason of your problem, I think I can at least present a work-around:
In bar 38, replace the sequence "dotted-half rest | tempo=50" by  "half rest | eighth rest | tempo=50 | eighth rest".
It seems as if a tempo change (and probably other instructions as well) needs a dedicated note to work on, which it doesn't have in your original notation: There, the two consecutive tempo changes both act on the first note of bar 39, with seemingly unpredictable results.

Thank you Horst, but the problem is much more subtle.
Try copying just a part of the score and the problem disappears. That's why I attanched the whole score.
The workaround is straightforward, but it's the bug that I want to show.

I agree. You can fix it with this replacement for bar 39:
Code: (nwc) [Select · Download]
!NoteWorthyComposerClip(2.75,Single)
|Bar
|Tempo|Tempo:50|Pos:11|Visibility:Never
|Rest|Dur:4th,Dotted
|Tempo|Tempo:140|Pos:7|Visibility:Never
|Rest|Dur:4th,Dotted
!NoteWorthyComposerClip-End
This is a new bug. NWC 2.51a plays as I would expect. It gives a time of 3:18 while NWC 2.75 is 3:37

A strange observation:
In the posted sample, mute any note in any staff before bar 39: Indicated play time goes to 3:18, and the odd tempo change behaviour disappears.
Mute any note in or after bar 39, and the odd behaviour persists.
Whatever that may mean...

Horst, I warned you: the problem is much more subtle than it seems.  ;)
