is there a line limit?

im making a game and i am at line 555, and I want it to play a sound at 5 seconds (or anytime I have tried) and it does not do it.and no matter how I change it up,on a button press even,it doesn't do it,so i'm thinking there's a line limit and everything past 555 is ignored?

I have had apps with over 1000 events. Have you closed out of Fusion and reopened?

Oh thanks.Turns out today everything is working fine today.Must of been memory issues with my computer.I do 3d animation also for the game for several hours before working on the game.I just need to restart from time to time.
