Issue description
It seems that at certain minimal levels it will be less then 0.1 unity to repair something. I'm not sure if it's actually like 0.09 and just not shown, and I doubt anyone would bother to abuse this even if it was maint 3, but still.
Expected behavior
Should either not allow repairing, be minimum 0.1, or show more decimal places.
Reproduction steps
Let something need 1 point of maint, look at interface.
Game version
0.4.12e
