How to reproduce:
1) have a timeline like this
2) put a slider after 1:28:000
3) save beatmap
4) run mapset verifier with negligible issues shown
And it will claim the inherited line at 1:28:000 "changes SV, but affects nothing", when it does affect the SV of the slider created in 2).
After some experiments I think this issue only affects the last inherited line.
