Looking at the mathcrap module (nice name :p), it seems the ² (and other
superscript characters) is defined as {\normalsuperscript{2}} and the
extra grouping makes the superscript to be applied to an empty base not
the brace. Not sure if removing that extra group is safe or not
(\normalsuperscript{2} on its own seems to be safe).
