Getting a strange error upon every new save with any alien race using Humanoid Alien Races 2.0;

Upon starting a new game and attempting to spawn in a colonist using devtools, I get the following errors:

RandomElementByWeight with totalWeight=0 - use TryRandomElementByWeight.

Exception drawing Ceti: System.NullReferenceException: Object reference not set to an instance of an object
at (wrapper dynamic-method) Verse.PawnGraphicSet.ResolveAllGraphics_Patch1 (object) <0x0032c>

Exception drawing Ceti: System.NullReferenceException: Object reference not set to an instance of an object
at Verse.PawnGraphicSet.HairMatAt (Verse.Rot4) <0x0001e>

The last of which is continuously spammed into the error log while the pawn is currently rendered
And prevent any sort of hair from appearing on the newly spawned human colonist

This not only occurs upon attempts to spawn in a colonist using devtools, but also on the "Wild man wanders in" incident as well.
It does not however seem to affect trader caravans.

No clue what is causing this but given it affects pawns spawned in via the wildman incident it is a bit concerning.
