Because this achievement was broken due to changes to how rolling interacts with player velocity and fall damage, we want to remove this interaction from the player's dodge roll. Thankfully, since Crea is written in python and its code is completely exposed, this is actually very easy to do. Simply navigate to steamapps/common/Crea/mods/core/system and open input.py with any basic text editor.

In input.py, there is a code section for the "RollStateHandler". Lines 2136 and 2138 of this file manage player descent and velocity changes; "comment" these lines out by placing a pound sign before these lines of code. Relaunch Crea; rolling should no longer reset player fall damage, allowing you to get this achievement as in prior version of the game.
