Stuttering and enemy does not take damage

Hi there, on regular base we experience - already befor the lst patch, the problem that my player character start stuttering.
Means when I go forward Im am "pushed" backwards a little bit.
From then on the enemy does not take damage when I fire on them.
This happens to all of the players in our community.

Today it was very often happening.

They had found a server issue but said it was fixed..... Well I hate to tell them it is not fixed and still just as bad ..
