zalmarath the colossus bug

Hey supteam,

i got a little bug i think is this normal? https://youtu.be/2Ts-SpAvTk4
I just want to make sure that the problem is fixed because in my opinion it is a bit OP.
you can only take real damage from the fist attack and you can do a lot of doge. Sometimes there was also a bug where you could no longer shoot Zalmarath the Colossus with projectiles. But you could with AOE attacks.
