Q: After loading the preset, some mods are still white or red, why?

A: This is normal and intended. Mods sometimes come with multiple modules and not all of them need (or should) be enabled at the same time. I have also disabled some optional addons because they don't quite fit the Zomboid setting (such as easter egg vehicles from pop culture).

Red modules are missing their prerequisite(s). These are usually patches that a mod comes packaged with, intended to be used with a different mod. Because that mod is not included, the module is red and disabled.

3/4 of mods listed in this package are Disabled even after I've put preset in correct folder. I'm not sure if this is intended

You need to place the files, then load the preset. Check the guide again or join Discord for a more detailed version.
