Actual scenario is similar. Just add/remove system breaks when observing last two pages.

Here is a probably minimal example. To reproduce follow these steps:
1) Open the attached score.
2) Remove the line break on the second line.
3) (optional) Remove the hairpin or make it slightly shorter. This doesn't affect the bug presence but it is even more prominent that way.
4) Change pitch of any note except the one in the last measure. Or do any other edit not involving the last measure.
Result: the hairpin appears where the third line was, and in the same state as it was in the third line.
