The game is in early access state, interactions and physics are being developed and currently they are on testing phase. Facial expressions are disabled temporaly due to new reaction system that will make character react depending their horny, lust, or item you are using at that moment.
Limited time events may feature characters for a limited time period, that's the cool part of limited time events, also we did this to test this kind of evets. The game contain the main characters (we add more characters every few months while we develop them) also for every character different outfits. So yes, we will made so much more limited time events with limited time characters, with this we add more exclusivity to this events.
