On the PC there is a limit of 255 Plugins and a few of those are used by DLC's, update and game save.
There are limits in place to help since on the consoles we do not have access to some tools to merge mods, easier means to sort the load order, etc.
It must be a pain to sort that many mods on the PS4. I find it a pain with only about 10 on the Xbox One.
Oh man, 208 mods without a program for load order sorting and problem detecting.
That's really annoying. Every time a mod updates it gets placed at the bottom. Wish they'd patch this
I have a feeling the OP is playing the load order more than the game.
