I have a few issues with the 8.3 test. I cannot seem to get Ashley to sleep in the MC bedroom after watching a horror film at night, there were times in which the game froze when MC was spying on Veronica before the Maid outfit was purchased, the clothing store at the mall keeps showing up with the Mall menu with the clothing store in the background, the perfume shop is having the same issues. The book you were able to buy in the original version is no longer in the bookstore and shows the night gown you purchase for Ashley, I bought the video game in the electronic store and it does not appear to show up on my computer, it is in my inventory but I cannot use it when I want to play a game on the computer, it just shows solitaire.
Unfortunately, 8.3 is a test of a change of how checkpoints are registered, and is only valid for Veronica (and even for her, the date option is broken)
You can interact a little with the other girls, but as you found out, almost all of their content is missing.
If you are new to the game, keep playing 8.2, and don't use the cheats except to get money and increase/lock your mood (hunger, sleep, etc), as that was the reason Faerin is revamping the checkpoints (people missing vital content because they cheated past it). And don't forget to sleep, instead of skipping time all over.
Hopefully, Faerin's personal life will get better, and the next version (8.3+, or 8.4) will appear within the next two weeks, and have all the old content + the new stuff he/she has been adding.
If you are familiar with the game, 8.3 test has couple of extra scenes for veronica. You can still break the game if you keep visiting Veronica at the club past 80 affection, and you can't buy a tuxedo for the date. The laundry scene is also "broken" in that it is repeatable the same day [ie, you can trigger blow job at 12 (10 minutes), cuffs and blindfold as much as you want (takes 0 time), and spank/bend her over desk 2 times (30 minute time lapse) all on the same 1 hour period].
