+## Error on Game Load:  Verse.GeneDef named rjw_genes_human_genitalia (wanter=genes)
+
+Error: Issue #4, Game throws a warning on load that some Genes were not found. 
+
+Reason: (Likely) because I removed some genes from Pre-Release to 1.0.0. Now some players have unknown definitions in their safe-files and Xenotype Defs. 
+The removed Genes were the ones that performed default behaviour (e.g. normal breast size, normal penis size, ...)
+
+Solution: Should be safe to ignore, when you get this on safe-load make a quick new safe. new safe should not throw the error. For Self-Made Xenotypes remove the Genes. 
+
+Sorry about this one, I know removal can break things but hey you were playing with the Prerelease!
