The ones that you can manipulate Such as: Queing an action like :Murder: on a target and waiting then as you get the xp you que it up again and again on the same downed target which sums up an infinite xp glitch.<NOTE> you will get A LOT of murder evidence.
also good for courting someone Like: Kiss>hug>gift if you're lucky you can marry them within a year cycle
Its uses are very versed and will give you a good head start.

Once my character was pregnant and had to go to court, she was due on the same time as the court. she went to court got sentenced to death, during that time she was still on the floor...when the time came she was executed after that she gave birth.

-Much like the ants that do a Death spiral, Carts,guards and some townies will do the same thing. Truthfully this one is good and bad but mostly bad, Only saw it occur during mid to late game. carts are sucked into that Death spiral and if you're a rogue/crafters its kinda sucks less materials going through the markets and less stuff being made.
-not sure how this happened but Employees not doing anything such as: not being able to attack a building,not being able to attack anything,not responding to clicks,NOTHING just total NOTHING, cannot be fired cause its an action. all you do is watch your employee waste away while you lose time and money :).
