EFP with cartesian coordinates failure.

Please let me know what what I am doing wrong. It seems that EFPs with cartesians are not read in. I condensed the problem to the modified  exam30.inp from the test suite, with some arbitary coordinate EFP. I am runing Firefly 7.1.G on amd64 linux box.

The error  message is:

I will paste the input file, it's short.

Interestingly, coord=int (e.g. exam30.inp) works fine!

Same error happens if I create a custom EFP, say H2OMY
and include $H2OMY card. In the coordinates are cartesian in
$EFRAG, it compains that "H2OMY does not match a standard fragment".
So, must all coordinates be ZMAT? For my purposes, cartesians are much
more convenient.
