[Bug/Issue] v0.75 - EditingDarklings/Ophidians Units

In my last game I was able to recruit Ophidians and Darklings units.

- I was already far in War research, so I found they were a bit underpowered by the time I got them. I think Darklings should be available far earlier for a lower research cost. For Ophidians, playing with Umber, I think it is great.

- So I tried to customize those units, and I don't think it is alright. First, when you click on female for an ophidian, you get an humanoid figure and you start with the base stats of the Ophidian.

- If you revert to male, you get the male mesh. And you can keep editing ang give weapons and armor. Then you get (too?) powerful units but I don't think this was intended.

- I think personnally this should not be allowed and that the benefit for those units would be the low cost (Wages seem to be 0.0, but I took some merchant traits and notably the one that halves wages). Allowing to build large stacks of ophidians or Darklings and so on.
