Hi glad that it worked, we can talk anytime here or somehwere else, dm me for discord.
My knowledge on chaos also similar, maybe its easier for me to understand what is going on since I am familiar with theoretical physics, not sure.
In terms of collision problem you mentioned, it would be better to go slomo 0.1 command, eject from player and alt+c to display collision are reacting where it should be. So that you confirm that collisions of weapon, projectile and geaometry collection are right. After that if issue still persists we can look some other places like simulation time steps and ticks.
