Does anybody know what happened to Stanislaus Madueke? All his activities ceased by the end of 2020. All his 20 repos are frozen in time with tons of PRs ready to be merged.

I have found a solution. Had to change totalForms on line 95 if hideLastAddForm is true:

line 95: totalForms.val(forms.length);

if (options.hideLastAddForm) { totalForms.val(forms.length + 1); } else { totalForms.val(forms.length); }
