Known information yes:
1. The loading of a save resetting the day is normal due to the way in which the variables are stored, this is something that was noticed since long ago but not much that can be done without an overhaul. Do note that is not that it advances a character by a week but that simply resets daily events, like Emma at the sauna, which gives that impression of advance.
2. Is a sigle time interaction, like telling Anna about Adrian. You need to have already done Anna raw at the studio and is only available for the slut route. This will be revisited.
3. The questlines do progress, but the issue is there was a mistake on the latest builds with relation to following of the variables for the log, which causes the log to either not be completed or be stuck on specific counts. Do note that the quests are still fine to be completed, but ofc you would need to know what to do. This is solved for the next version.
