Can someone please help me?
When I try to create a world the game crashes every time.
The full error:

(I'm using google translator for this, sorry)
There is an error happening in some XML file of the game that does not allow me to create a map (every time I create the game crash) and I am desperate to look for help
The error:

XML error: <defaultLabelColor>(18,215,57)</defaultLabelColor> doesn't correspond to any field in type ThingDef.
