Synchronization is a Problem
I have noticed many small glitches, like the way guns fire and hit targets and other times don’t. The way the client tells you how much time you have to use a stim but it is actually different. Health bars are another one. There are tons of these little synchro issues that can be the cause of a lot of the game play problems people are posting about. Even my post of the doors shutting and blurring on me could be related to server synchronization in some way.
Cordially,
