casm super --get-transf-mat returns the identity matrix

[xivh]

casm super --scelnames "SCEL...." --get-transf-mat --unitcell "SCEL1_1_1_1_0_0_0" always returns the identity matrix regardless of the scel selected. Also, if it is called without a unitcell, it crashes

casm super --scelnames "SCEL1_1_1_1_0_0_0" --get-transf-mat

CASM: Uncaught exception: 
std::bad_alloc

Running the command repeatedly works occasionally, but the output does not make sense:

casm super --scelnames "SCEL1_1_1_1_0_0_0" --get-transf-mat
