SMARTS matcher does not recognize all aromatic atoms in:

Logged In: YES
This error was caused by a bug in the aromaticity typer.
The typer uses default bridging root atoms for
double-checking the pre-assigned aromaticity flags. If the
root atom is trapped by two other aromatic ring atoms, this
can cause false negative detection of these bridging ring atoms.
The bug fix tries to avoid bridging ring atoms for
double-checking aromaticity, if this is not possible a
warning will be shown for this molecule. This warning can
only occur when the treated rings are inner rings, so this
should not be a serious problem, because if the outer rings
are aromatic, the inner ring must be aromatic, too. Anyway,
the warning will be printed !
