Hi,

this message is an indication that something went wrong during your system
setup, most likely connected to the heme parameters or linkage to the
protein. A non-integer charge system makes no sense to simulate in my
opinion, as it does not correspond to a physically existing state. I would
investigate if your partial charges are really assigned ok.
