[AMBER] You won't believe what happens with maximum coordination limits...

Hello everyone,

I've for some reason decided do something with Ferrocene in Amber, because
it is fun? Anyway, tleap is kicking me a wonderful error when i try to
assign the ten bonds to the iron center:

> bond x.1.Fe1 x.1.C32
Bond: maximum coordination exceeded on .R<MOL 1>.A<Fe1 54>
      -- setting atoms pert=true overrides default limits

And so I responded to tleap:

> set x.1.Fe1 pert true
> bond x.1.Fe1 x.1.C32

Which then I got the rude reply:

Bond: maximum coordination exceeded on .R<MOL 1>.A<Fe1 54>
      -- setting atoms pert=true overrides default limits

On the off chance it could be reasoned with, I pleaded:
> set x.1.C32 pert true
> bond x.1.Fe1 x.1.C32

Yet to no avail. Is there a hard-limit on the maximum coordination of an
atom type? or is it possible to change this limit somewhere/someway else?

Thank you kindly,

-David
