This seems to have happened with glissandos in the past, but the issue still seems to remain with slides.
To reproduce, create a score, enter a note, add a slide and move it, save the file then restart MuseScore.
The moved slide will return to its original position.

I am using MuseScore 2.0 by the way.
I have also tried the latest nightly (MuseScoreNightly-2015-04-03-1408-42bdb5f)
