Maybe a temporary glitch when I wasn't looking. Strange that they all ended up outside the edge in both sims. I had checked the boxes for slow movement, but they had unchecked themselves.
Maybe if any of you are planning to start fixing bugs again you could go through the guis and make sure all settings do what they're supposed to do and that they stay put.
Disable Vision on the Species tab and Graphic Update Interval on the General tab are not saved in sims and Pond Mode settings reset whenever you re-open the gui.
When you hover your mouse over several places the wrong info is displayed.
Just pointing it out in case you feel like taking a look at it.
