Ranger bow/crossbow bug disarm while attacking

There is an very annoying bug with disarm for ranger using crossbow/bow while attacking while swarmed by many monsters and while attacking you press by accident (unavoidable i even disabled items to show but when you hover with the mouse over while attacking you kinda pick it and IT disarms you leaving you without beeing able to attack and that leads to death 99% of the times, i saw that others had this bug too, hopefully you can fix it fast I die in breach for example everytime i get this bug and happends pretty often please fix this)
