Hello, The following minimal example yields an error using the latest version from the garden: \starttext This is before \in{Figure}[fig:cow] \startpostponing [+0] \startplacefigure [reference=fig:cow] \externalfigure [cow] \stopplacefigure \stoppostponing and this is after. \stoptext tex error > error on line 3 in file virtual://page.nopage.1: ! Extra }, or forgotten \endgroup \strc_floats_stop_place ...unwantedspaces \egroup l.3 \stopplacefigure <empty file> The problem appears with the use of \startpostponing\stoppostponing (used to prevent a paragraph break in the middle of the sentence).
