Rat and Gobble Problem ?

[lppurdy]

Hi

 I've entered the sewers at both entrances and can't attack the Rats and Gobbles. If I use
the /attack or shortcut System tells me Rat is impervious to attack. Is there a problem
today (May 17 ~ 1:20 EST) ? Or is it just me ? If me how should I proceed to maybe fix ?

                                                      Thanks in Advance

sometimes the npcclient crashes and that happens you just need to wait for it to be put back on.
