Okay, yes. The mod may cause performance issues in areas with a lot of zombies. I play with a small amount of zombies. And, to my own regret, haven't found a way to achieve a similar result otherwise. If you are severely bothered by performance issues, your only option is not to use this mod.

unfortunately causes insane performance issues :(

Give me a few hours to think about it, but it will definitely happen in the next day or two.

Ok, I'll rework the mod logic to consider such situations.

ok got it

It would actually be a neat mod in its own right. Have them stand still while you look at them but immune to damage but then you look away they sprint at you on some doctor who shit.

So I've tried it with only your mod. If you set your settings to Speed = Random and Day/Night effect = Day. You get the behavior where the zombies stand still when they have agro on you but only if you are looking at them.

>Can you please add sprinter to the option
Beforehand - no, this mod was supposed to be very simple and perform only one function under strictly defined conditions. But, in general, it's made quite simply, and inherently can't cause complex effects. Given that you're using some other mods, it all comes down to the fact that it requires testing.

This needs testing, but as far as I've been able to understand, what you're describing can't be caused by this mod. It should ONLY work if speed is "random", and if a specific zombie is defined as a slow shambler, it changes its attribute to fast shambler using the workaround I took from "Add Random Sprinters"

Tbh I'm not sure. Im running a couple of other zombie mods. I think its the day/nght effect causing them to bug out thought or if you try to change the settings.

Can you please add sprinter to the option and not just random? I'm trying to get fast shamblers during the day and sprinters at night but the day/night effect puts them in slow shambler mode during the day and its annoying lol.

I didn't find anything majorly wrong but I did find something weird. It probably because it was a save without this mod enabled when created. And It not being used correctly. If you change to speed to sprinters and have the day or night active effect thingy on. They will appear to just stand but they are still traveling and will appear once they get in hand out range. If you get in close range they will do that hand out thing and will move correctly.

I didn't test if it's compatible or not. Update this mod, then write back if it's working.

Cant use with starlit library?

AWESOME!
