I've made a mod and whenever I attempt to load it up, i get this error in the attached log. The game then crashes immediately after the Chucklefish logo. As far as I can tell from the log, this isn't attached to any particular file. I tried testing the installation without the mod in the folder, and it loaded fine, so I have definitely isolated the problem to the Saiyan Race Mod itself. Attached is the starbound.log and a zip file of the mod itself.
Your .species file is missing a property, "characterCreationTooltip." Here's a sample from the Avian.species file: Code: "charCreationTooltip" : { "title" : "Avian", "subTitle" : "He", "description" : "Avians are a race of colourful birdfolk whose tribal culture revolves around the worship of Kluex - the winged god of the Aether. Their soldiers are trained from birth to be fierce warriors who will protect their temples at any cost." }, Note that the log does explain this. If you look at the lines below the JSON error, you can see references to the Species database throwing the error.
