Strange Bug - Race won't repair

[primitive]

The Primitive Horde, much like the Primitive himself, do not know how to repair stuff
I have been using the same race, with only a few minor modifications, in KOTH for quite a while now. After the latest edit and save, the Horde has lost its ability to repair. This is true for my current game (makes retrobuilding kinda hard), but also if I try to edit the race more.

Anybody else seen this?
Any ideas to what I could have done to screw this up?

If someone wants to take a look I can send the race file.

BTW
The race is Berzerker with 70 % to repair, which usually repairs 3 components/turn on a SYI
