Getting shot through walls

[Getting shot through walls]

I've seen this also lately but when it happens shouldn't the little red chain icon pop up indicating it?

When it happen to me I was in a airfield hanger, guy comes around the corner I pop 3 into his back with my AK. Next thing I know I'm dead, never saw him fire a shot or even turn my way, and as I lay dying he goes down too so I know I hit him.

Another time I met up with someone and it looked like he was lagging all around, he would glitch in and slide all over. I had a 16ms ping on the server and his was fine also. I asked him if it looked like I was gliding all around lagging and he said no, but his character never caught up for me it was always un-sync. Still never saw a red chain icon..

[Low zombie count/low loot across servers]

It seems more like a bug then the servers reducing for performance. For the past couple nights I've been on the seattle server. The zombies run about 200~ and eventually drop to 0, The server isn't packed maybe 20+ players but everything stops spawning.

Pre 1.5.6 patch it was a constant 700+ zombies, hardly see over 200 now.
