I have the same issue with all maxed-out units. I googled the problem, but no one has found a solution. In general, the most important thing is to perform absolutely all animations in one go, and do it correctly. It's very inconvenient, of course, but I can't do anything about it...

The problem is that you can't import animations through the editor so that this parameter is set automatically. It seems that CrazyPill withheld some files for their export through the editor.

Does this parameter control the movement speed on the map? That is, how quickly does a creature "jump" from one cell to another?
