Question do the modloader mods not function with your KittyPatcher mods? At least currently modloader seems to function with 5.4f where as when using the newest KittyPatcher the game changes to version 5.4g and modloader just disappears. Further while you say in your main post about mods that the other mods not done by you require modloader, I noticed in the GoogleDrive of mods that NPCVisualization and others are there as .mod files. Even when adding in the necessary images for the NPCVisualization mod that mod doesn't function.
I have also tried downloading the HTML version of NPCVisualization but trying to add your mods by patching the HTML causes NPCVisualizer to no longer function. Is there anyway to use NPCVisualization alongside your patch mods?
Modloader mods that don't conflict with my mods should work perfectly fine.
However, important to note, KittyPatcher/CourseOfTemptation.exe only works when your html reads "CourseOfTemptation.html". So you have to rename modloaders COT html file in order for both to work.
I made a KittyPatcher version of NPC Visualization so that you wouldn't need modloader to use the mod. However, you need to download the res folder with all the images or else the images won't show up. I don't recommend using modloaders NPC Vis and KittyPatcher NPC Vis. You'd have to use one or the other. Of course, you still need the res files either way.
I've had no problems with NPC Visualization and my mods. They should work fine together, if they don't then it's best to start from scratch with a clean setup.
