I noticed this only occurred with the new Beta 4 switch to separate Auto-saves from Manual saves, but now neither type of save is ordered by date anymore. Which makes it virtually impossible to pick your most 'recent' saved game simply by the order of the saves. I used to really like Auto-saves since they were... well AUTO, but now with the ordering schema going 1,10,11... 2, 20, 21..., 3, 30, 31, 32, it's rather obnoxious to even track down 'close' to the right save.
Also, similarly odd, try selecting any saved game, viewing the profile screen with the team members, etc, and then click the back button in the bottom left portion of the menu. Then click it again. then click it repeatedly as the maddening frustration of the fact you didn't REALLY want to load THIS game because you couldn't tell which save was most recent and now there's no way to pick a DIFFERENT game to load because the back button's only there to torment and manipulate your fragile psyche.
In anycase... minor bug/feature/unpleasantness. But i was surprised a search on the subject didn't turn up any similar findings.
