I was hunting Hime's (Dreaming Ghosts) earlier and suddenly, despite attacking (with both Heal and Shining Ray), it'd not register them being hit. I was attacked as normal, but I couldn't hit them (despite hitting them just moments ago). The bug disappeared once I moved a little (it wasn't lag, as I was constantly attacked and healed myself). This has happened 3 times in a row now. It seems to happen around when I level up. The other bug is that when I attack Hime's, they keep floating back and forth until they die. They do nothing to try and attack me. This only happened once. And no, it wasn't a different Hime - it was a freshly spawned once that I kept attacking until it died, with it never attempting to counterattack.
first, if you dont move and keep healing/attacking for too long, it will "lose" effect, it will stop attacking. it happens to ALL classes and ALL attacks if you stay still for too long. for example, if u kill anego and stay still for over 1min just attacking it will sudenly stop attacking. since u cant stop healing, because the effect will still show, it will stop doing damage. for the second problem, u are just not dealing damage enough to knock back it
