I wouldn't call them super settlers, the buttons don't work if you don't have enough PW these tile improvements and the necessary advances. I just can't disable them, if you don't have everything. Also other units have them but in most cases other orders lay over these ones.Originally posted by ETB
The other odd thing that I have noticed is that settlers (and slavers) have special buttons for building airbases, forts, and other special tile improvements. See the graphic below for a sample. These are super settlers indeed!
For the crash problem I have to look into the script files Pedrunn gave a hint somewhere in the forum where the problem could be. For 0.993 version did you used any updated slic files I provided here in the forum.
