Last one! For Titanium if you enable the Quality module but not Space Age, then there's a load error when titanium tries to modify the recycling recipe. I only ran into this while testing, no idea if anyone is doing runs of the game with quality enabled but not space age.
I also noticed that the Titanium plate recipe doesn't have auto_recycle=false set, though that only comes into play when I modify the recipe in Wooden Industry to not be smelting (since smelting-category recipes are never considered for generating recycling recipes). So I'll make that fix from my end.
