Hitboxes broken since latest Gmod Update

[NovusBal]

If you read the title itself, you'll have an idea of what i'm going to describe.

Basically since the latest update the hitboxes have been acting incredibly weirdly, in such a way that is affecting players and the overall gameplay.

Here's some additional information:

Gamemode: Zombie Survival (JetBoom's public version)
Server IP: Connect to either 185.38.148.118:27015 or 185.38.148.76:27195 if you want to test it.

Back to describing the problem at hand;

The hitboxes are fine if the players run in a straight line, but the moment that a player jumps, crouch or any actions like this, the hitboxes become out of place. Here's an example, a zombie can attack a barricade whilst crouched, with only his head being viewable to the people behind the barricade. They shoot, the bullets go through as if it's not there, so it seems to be lowering the hitboxes during certain animations.

This did not happen until the most recent Gmod update, and happens across multiple ZS servers so thankfully I can justify that it's not just an issue i'm having.

If someone else with a better insight to what is causing or how to fix this can help, it'd be much appreciated.

[Side note - I do not play other gamemodes so unsure if this is the case for others]

This is a known issue with crouch hulls and is being investigated by Robotboy.

Well thank goodness for that, it's becoming quite the problem among the community.

I'm guessing this is affecting other gamemodes, may I ask to which extent?

To the extent when a gamemode uses a different hull sizes for players.
