I'm having this issue as well.  I'm still researching.  All my units seem to only have a move of 1 now as well, which may be related.  It takes a while to get anywhere this way.  I'm wondering if it's old saved scout unit designs or something.

I deleted my old custom units and had no scouts available at all, which is probably what RPMF would get if he deleted his Units folder.  Everything still had a speed of 1 however (including enemies), which is very weird.  I then did a complete un-install and re-install of the game and got the same problems, as well as dog-slow game speed, which was odd, it's always been reasonably snappy for me.  It's faster in windowed mode however.

I have done an uninstall (via impulse), and after the new update I only have soldiers as units.

Also in the design unit section a strange graphic problem occours, like there is some swepping on the screen and like you have a 'mad' clock with the pointers going arround very fast.

I have windows 7 pro 64bits, were can I find the debug.err ?

how can I do a total uninstall ?
