ERROR in check_subsys_element (MODULE topology_util)

[jadefox337]

Hello,

I am running a standard geometric optimization, except that I am
placing an optimized group of HCl + 4 water on a sugar.  The optimized
group is in fact ionized HCl that turned into Hydronium+, Cl- and some
water.  The program fails with the following  (where 59 is the index
of the H of the original HCl and which is now connected to a water):

Does anyone have any idea how to fix this problem without actually
moving the H near the Cl (which by the way I did already, and caused
to crash without error explanation - some *btd files were created).

I can supply input if needed.

Thanks much,
