I posted a second version of each yesterday with original ship sets that came with the basic game on Workshop. They are listed as "", i.e. Ugor 2, and Arcane Conservancy 2. If they are not working, I am at a loss as to why, seeing all others work with them. Possibly it might be the new planet or the “Scavenge” ability, both are used with the Ugor. Neither was used with the Arcane Conservancy. My only question is do you have v1.3, and the DLC "The Revenge of the Snathi" and "Mega Events" ? I am a founder and I automatically get all DLC. Possibly something else I got in one of those I am using without noticing, such as a color, or something else. All I did was change the ship set and nothing else.
I don't have either the snathi or events DLC, but I am running the current patch (1.3).
I am sorry for all the trouble you are having. You could easily produce the race with what you got off Nexus by putting the FG, BG, logo, and portrait into the matching folders in the factions area, then just make the race for yourself. The download from Nexus has a "pics" folder with pics showing all the information and what to put in.
I did not change the mod on Nexus, only created a second one on the Workshop. If you recreate the race using the Nexus mod, only copy over the four PNG's I referred to.
That might explain it, I don't know what the workshop is or how to use it, I just downloaded from the nexus.
In terms of recreating them, what racial options did you pick for each race?
And don't worry about the inconvenience, I am enjoying all the other factions, even with these two not working for me there's still about a dozen that do work. ^.^
