Are zombies more bugged since 1.7.2.5 ?

[schrapple 119]

Since the latest patch I've come across some strange zombie behavior that I haven't seen before and I was wondering if anyone else has seen it? These are some of the things I've noticed.

1. Invisible zombies, been killed twice now by zombies I can hear but can't see.

2. Zombies that see and hear you from massive distances away even though you are crawling (like literally so far away you can't see them).

3. Zombies going aggro at nothing and then calming back down in a few seconds

4. Zombies running at aggro speeds even though they aren't aggro

5. Zombies getting stuck under floors and passing through walls.

6. Running up and standing in front of zombies and they don't notice you at all.

Has anyone else noticed these sorts of behaviors?

How about trying to shoot a zombie in melee range and he teleports behind you to the side of you and 20 ft away and back again?

the only strange (or what i'd consider "unintended") behaviour I've witnessed has been when you hear a Z but can't see him anywhere. Usually it turns out they're buried within a structure, if you get close to the walls you can sometimes see their arms poking out trying to grab you.
