HitBox is basically uneffected, 1.7.10 issue (looking for a fix i can do not the mod creator)

[DragonBlood121]

Hey so i have an issue where if i morph into a mob smaller than the player model there is a small hit box where the player models line of sight is that interacts with the world and makes it hard to fly through small openings 1x1 2x2 or 2x3 i have to line up the hit box just right and if i don't my character dies of suffocation. is there anything i can do to fix this maybe install a difference version of the mod from 1.7.10 because i have the most recent 1.7.10 version from curseforge. or is there a mod confliction causing this? i am playing crazy craft 4 from the Void launcher. has anyone else had this issue?
