I just got an error in one animation that changes the alpha of an image when trying to run it in my libgdx game.

Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: java.lang.NoSuchMethodError: com.badlogic.gdx.graphics.Color.set(FFFF)V

Im using the latest nigtly build btw. I think someone changed the Color.set method

oops! my fault, I was using the latest libgdx and spine-libgdx 1.0.18. I've switched to the latest spine-libgdx and it works like a charm
