is this bumpy, "Up and down" road problem in the base game or is this due to a mod? im going schizo over it and want a fix

[faentaallmods]

so i've been working on my modlist for 5-6 days now, lost all my work yesterday and had to start over and now im done but i cant enjoy my game because the constant up and down movement and the ugly bumpiness of these roads are driving me absolutely schizo. i dont have any more mods that modify the ground than my first modlist which i dont remember having this issue (that one had norther roads though so maybe that NR fixed the issue). i have tried disabling all mods i know would modify the road and even went into vanilla skyrim and its there too.  does anyone else have this or know how to fix this (i have blended roads but it does nothing) there were 3 bumps in vanilla oiutside the door after the dragon collapse but i feel like this has a lot more bumps https://imgur.com/a/jw74CaA . can anyone tell me a solution or verify their modlist/vanilla?
