What in the world was going on in that middle picture?
I really don't know.
My sim was about to hit level 9 in science, and I got all excited since that was his lifetime wish (become a Creature-Robot Cross Breeder), when the game got really buggy.
They all got out of work, but I didn't get a notice of money earned, promotion or anything, and every sim (in the entire town) was frozen.
Poor Max and his coworkers all left the building at the same time and got stuck together.
I tried resetting a couple of them, but that didn't work.
When I reset the wife who was frozen at home, she teleported to the garden, walked a few steps towards the front door, went invisible (camera still followed her through the door) and then teleported outside again and got stuck in that loop.
Going through several save games I couldn't find exactly where the game got bugged, so I started a new game with better traits etc from my experience so far and didn't encounter the bug again.
Since Max was about to hit the Creature-Robot Cross Breeder level, I fancy his experiments took a very wrong turn.
In the new game he made it to Mad Scientist and I like to make him whip out his ray gun and zap everything in sight.
I even experimented with giving him evil/insane/inappropriate traits to see if he would do that on his own, but no luck so far.
