I'm on the "Breaching Security" Assasssin quest, which requires me to follow a NPC from town to town based on time and day of the week. The issue is that the in-game calendar switches from one day to the next at 3PM, so that when the NPC should be at one location he's actually on his way to another location. Very frustrating to say the least. Please fix the calendar. Thanks.

EDIT: Sorry to clarify that this 3PM issue only happens when "waiting" or fast travelling. Thanks.

EDIT EDIT: Also noticed the calendar flips to the next day after 3PM when going through a door that requires a auto-save (like city entrances).
