All of the big mega-mods are compatible only with older versions of the game. 4.12.2 is usually the newest they support, with some supporting only older versions. Highly unlikely any of them will work with 4.13.3.
Alternatively, there is a mod activator that is available for 4.13.3 (found
here). When using the modactivator you pick and choose which individual mods you want to use.
I personally prefer the modactivator myself. The big megamods just carry
way too much unwanted baggage for my preferences.
