XenoVerse 2 mods limit

I'm at 321 mods installed and I know I can go beyond this limit but i keep getting warning texts from the installer, it says that there is some kind of problem with adding new skills with the mods I'm trying to install and then it closes and doesn't install the mod. Maybe i have too much mods with custom skills? I don't know what to do. I hope someone will let me know if there is a way to avoid this thing so I can install more stuff 🙏
