Hello Aric. I'm having Issues with the install. I have watched the Video and done it step by step several times however I keep ended up with a game with no starting slave and I am unable to buy new slaves at the market.
If you’re having repeat issues, I recommend grabbing the “Strive v5.25 with AricsExpansion v0.9.7” from the link in the top post and use that install instead. Then you just need to make sure that AricsExpansion (named exactly that, not renamed) is in the AppData/Strive/mods folder. Then you activate it in the mod panel, restart, and are good to go
I look forward to it. I don't think I've said it before, but I absolutely LOVE your mod. I enjoyed the base game, but your mod adds so much. The only thing I wish is that there were more preg/nude picture packs, I've only been able to find one.
This is a known bug and fixed for the next version, but currently it's preventing breast size expansion during pregnancies. You can fix it by going to your Aric's Expansion mod files in the appdata folder and in expansion.gd on line 1771 change 'globals.titssizearray.back' to 'globals.titssizearray.back()'.
Not exactly certain of how you managed it, but you have an error on line 2594 of a file that should only have 1846 lines. The only way I can think of for getting that result would be using the patch files portion("Put in Strive Game Files") of aric's mod as the mod folder. The entire "AricsExpansion" folder is generally put into the "/Strive/mods/" folder, though the portion you have there can be left out.
Depending on how it was done you may have corrupted the pre-merged Strive program folder and may need to start with a fresh extraction. Otherwise you may be able to un-apply all mods, correct the mod folder, and re-apply mods.
FYI, that thing is not in, nor have I forwarded the tweak to Arcis yet, but I will. I've been busy the last few days (job interviews and preparations, leaving my old company).
Don't expect much, it just expands the player (and companion) actions a bit, so it takes into account you (companion) sex bits and hopefully fetishes, and so playing as female you don't get "you enjoy their body immensely", and that's it.
But, since the thing is a text file, it can be edited and changed.
You are probably using the pre-merged version of Aric's Expansion, but that version still requires several installation steps. The pre-merging simply lets you skip moving the contents of the "Put in Strive Game Files" folder and deleting the "backup" folder.
The races are not showing up because you did not apply the AricsExpansion mod to the pre-merged version. It may tell you that it is already applied, but that is because v0.5.25 of Strive did track mod installs per instance of Strive; there is a single record for all instances of Strive on the computer. Simply make sure AricsExpansion is selected and press "Apply" again.
The first post in thread had a video of the steps, feel free to mute it. If you are using the pre-merged then it will not quite be accurate but you can start at about 1: 43 (YouTube Video). From 3:14 to 3:52 it will show how to move the "Put in Strive Game Files" folder and rename "backup" folder, SKIP this part if you have the pre-merged version.
Chances are strong that you have the wrong folder path. But if you are unable to resolve it then I recommend joining the Strive Discord (/t/284398/discord), where we can walk you through the installation steps.
When I select one of my daughters it instead selects the last slave I selected before her, it gives me this error: 
Also noteworthy is that her race is listed as just "Halfkin", my character is a 100% Taurus, her mother is a 73% Feline 27% Fox Beastkin Cat.
Bringing her to the slaver guild and trying to sell her creates this error:
