It's not a big deal for me, but I've found that no matter how many times I click a preference for my villagers, the next time I go into the game, it appears that I've not selected a preference for them.

Also, sometimes when I switch between tabs on Firefox, I go back to find some or all of my villagers walking in place and the hand frozen as well. If I move the mouse, I can see other things being highlighted but the hand doesn't move until I click on something else. The people also do not become unstuck until after I click and drag them elsewhere.

Another problem I have is that I can't see the mouse moving around after I click on the quests and try to go to click on OK. I've also had that problem after clicking on the shop. This doesn't happen all the time though so I'm not sure why it's done it.
