Any update on a fix?

Great work Mr Geez

I would also like to see an animation when pulling weapons from inventory.

They're not just a little harder. They've done 3 separate alterations to buff them, and each one isn't small.
-Firstly, they've added a 50% damage reduction to the zombie head when using melee.
-Secondly, they've made it so zombie attacks hardly ever get stopped by your attack meaning even with 1 zombie, you'll most likely be hit more than once.
-Thirdly, ALL tools have been incredibly nerfed in damage.
Combine all 3 of these changes together, you have zombies with a head twice as strong, "high damage" tools that are half the damage compared to the current build, and zombies that will constantly hit you whilst you try and wonder what is happening.
