Thanks! I'm considering tweaking Mortimer and Don's designs a bit more in future updates, since I do like some elements of their new EA designs, but I'm not planning on doing any more versions. It's actually a giant pain, lol. But they will most likely end up closer to their EA remake designs in the next update.
When you load into the Goth household, Bella should have the abduction milestone already (so long as you have Get to Work), and if you also play with Aliens Reloaded there's a few easter eggs. More when I release the AR 4.0 update. You'd need to have both AR and this installed when beginning a new save, though.
