Something broke with formula numbering, and it is due to the numbering changes. \preparethenumber is commented from core-sec.tex, dododoformulanumber in core-mat.tex still uses it. As a result even the simple \placeformula \startformula a = b \stopformula fails with ! Undefined control sequence. \dododoformulanumber ...@fmleft \preparethenumber \??fm \composedsectionnumb... <argument> \normalreqno {\doformulanumber [][][]{} } \secondoftwoarguments #1#2->#2 \dostopformula ->\doplaceformulanumber \getvalue {\e!stop \formulaparameter ... l.3 \placeformula \startformula a = b \stopformula Changing preparethenumber in dododoformula by preparefullnumber gets rid of the problem.
