If you have bug reports please put them up on the Github page so I can easily track them. As for your earlier questions, I can't say much about the actual logistics of it, but while I don't think that anybody's made Argonians for StarBound, I feel like they could be modded in like any other custom race. If so go into your Starbound mod folder go into the 'StarboundSimpleVoreMod'' folder and there you will find a pred chart to help you spawn in NPC's. I’ll have a post tomorrow about a new method to updating.
And the custom belly clothing, technically most of the pred tenants have an alternate 'full' clothing sprite that you can spawn in. You should be able to access the 'Foodhall' via the Teleport shop in the Outpost. If you can't you can spawn in the Foodhall stores with these codes. I’m sorry the time you had to wait for this doesn’t match the content. Feels like I’m stepping on eggshells now. Okay, that Vicar one is deeply impressive.
