With the Unique Grasses and Groundcovers mod installed, i receive an odd jumping/gravity glitch. Everytime I jump, i do not gain any height. I don't fall any quicker, yet I will take severe amounts of damage from a short fall. I run this mod through Mod Organizer and I have manually modified the grass section in the Skyrim.ini This is also the only mod I have that has an attached ini. Any ideas why this is happening and how to fix it?
