@Lucilya You've got it right. That's the fix, and I thought I purged them all. I can't find where I've still got that in the patches or main files.
@slippa666 Can you try Ctrl+F for .taurus in expansionsetup.gd as Lucilya points out, and see if you can find any .taurus that needs to be .cow? If so, please replace it and see if that helps.
