Chibi_Ultica knife spear graphic missing

[TheAnay256]

I'm using Chibi_Ultica and as of an update late last week, the graphic for "knife spear" (the real one, not makeshift). Used to have the same graphic as "steel spear" and in its json you can see: "looks_like": "spear_steel",.

Steel Spear does have its proper graphic, so maybe something's going on with how tile fallbacks are handled?
