Hi! Complete beginner, and I fully understand if you are not offering technical support for this pack, but I'm experiencing a crash whenever I jump, then land on the ground at (I believe?) the same frame the hitbox comes out and makes contact with the other player object. Below is the crash log. I'll try to fix this myself once I have time to actually sit down with the tutorial, and will post the solution if I find it, though I know next to nothing on the topic so, we'll see. Thanks!
