It was hard giving this a title because i am genuinely so confused on whats going on here.
I have a tank which i’ve made work and by me i mean chatgpt 
because i am not this advanced. Anyway whenever I test play, i can shoot once perfectly fine but then when i try to shoot twice the explosion just happens as if its hit something invisible.
I’ve tried disabling cancollide on all parts of the entire tank to see if that was causing it but thats not it.
