So I know this is something you are working on right now but I just wanted to point out if you didn't already know an easy way to check for alignment issues ingame. If you press F3 twice ingame it will mirror the animations, so it shows you what each direction would look like on top of each other. As you can see in the first image below, most of the characters are standing and facing themselves, which is obviously not ideal because the collision rects and their WorldCenters are lined up with the middle of the animation, if they are too much to one side then everything gets thrown off. You can see this the most in the second image with the Pirate being way behind where his actual collision rect and WorldCenter is (the WorldCenter is the little black square in the collision rect). In the third image below, some of the animations are lined up almost perfectly on top of themselves, although this is just for that specific animation because other animations look more like the first image. You can easily test any changes you make by just running them through the converter, no need to upload your changes through Visual Studio, once they've been converted they should be reflected ingame immediately, and you only have to upload your changes when they are finished.
