BUG: Can't attack until I log or zone... please wait until previous action completed

GRRRRRRRRRRRRRR!!!!!

Some Monsters are bugged. If I attack from just outside my range nothing happens, it looks like my attack has started.

Then the mob will figure out it has been attacked and then I get the message "please wait until previous action completed ..." then I cannot attack after that until I log or zone

This definitely affects the following monsters in Clon****: Any reptiles, Fallout Taipans, Emerald Viper, Mudevil Salamander, and Sabretooths as well. It does not affect Reets or Leets.

This has happened so many times, I had to change where I was hunting
