Standard asset explosion not working?

Basically i have an explosion set to explode when the game timer hits zero. yesterday everything was working fine but now for some reason the explosion isn’t working. I’m using the explosion from the unity standard assets. My main problem is that when the explosion happens the particle system is working but the force itself isn’t. yesterday i had it set up and when the timer ran out everything around me would fly away but now the force isn’t effecting anything. I’ve noticed that the explosion doesn’t work only when it’s a child of my player character. This set up was working yesterday but now for some reason isn’t. HELP

[SOLVED] Rebuilding my project got everything working again.
