wall bug?

i notice sometimes, i can detect where the enemy is hiding behind the wall because i accidently move mouse on the wall and see the cursor goes red, is this because of lag or what is it? this is not the same as in Waterfront you can see enemies through some doors

Never happened to me, sounds pretty legit though

yes it happhen to me lol some times when texture are not load at all

Happend to me too. Don't know how it happens but I know you can shot the enemy too if you stand in the right direction.
