Alright. I can explain the logic behind the movement modification. For example, I wanted to fix the jerky animation of Kujin, but she is the only female Orc hero in the game who rides a buffalo, and she only uses one movement animation. If I try to link the animation of other Orc heroes to her, it doesn't work because it's incompatible. Perhaps if an enthusiast with experience in working with in-game animations is found, they could rework it manually, but for now, we have what we have. As for mods that replace hero models, the animation is often tied to the model, and it is really important that the movement points of the models match.
either the movement speed in space is recorded incorrectly, so the model makes a sudden jump at some point, which can be fixed;
or the animation itself is jerky, in which case I am powerless – it will be even more damaged when converted from gr2, it will be rewritten again in Blender and damaged, and then it will be slightly more damaged again when converted to gr2. With my animation tools, I can only break things
