check your splits. You can program events and if you have an event too much it might activate before the event you meant to activate. I had that at the garage after birkin fight.

Your timer is still comparing to real time (normal time) but it has to compare with game time (it stops at cinematics) Go to layout settings, then timer tab and you should find it.

looks really cool and fits the game perfectly, was it kind of hard to make or was it alright?

Is having the rocket launcher in your inventory even allowed for it to be in the leaderboards then?
