How come my character super launches when I jump on another character?

This is a really simple question. I haven’t seemed to figure it out. It’s basically whenever I have collision on and lets say I make a copy of original ttp character. I play, I jump ontop of him and I launch 50 ft in the air. If i add a sword with collision sometimes either of us will launch 1000 ft into the air. Does anyone know my simple problem :confused: if you open a blank project youll get the same thing if you really wanna get into it… easy karma points i guess :slight_smile:
