Same here! This is a major problem for those of us using the Chicago/Turabian citation method (i.e. many from the Humanities amongst others), as we don’t use in-text citation at all.
It seems that the patch fixed the frustrating problem of there being no dash for texts in the bibliography with the same author, but now doesn’t allow us to actually place any citations in the document at all. All my previous citations work fine, but it doesn’t allow me to add. Neither does it allow me to unformat the citations and reformat them, giving the same error message.
Very frustrating when we have papers etc. due soon - I hope they can get a fix asap!
