Commenting on what's happening currently.
Recommend watching the
Stream Highlight.
If your internet is bad or twitch issue or something then just read on... kinda breaks it down a bit.
Nitro is at
Charmed Ridge and he has encountered an issue which is the level's bottles don't pop.
When Nitro enters another area of the level (not entering sub sections) (remember bottles popped) the effect of the gems exploding out is not being played until he physically stares at the position then they explode but only then.
When Nitro takes his time as if it is a timing thing with the gems the same issues occurs.
The most obvious one where it fails too is entering Sgt. Byrd's section and exiting it they return to the bottled state.

Anyways, possibly my only suggestion is do it without that speed proxy you got besides a re-route.
