Thank you @akapowl for your reply. I tried this, looks like it's not the problem.
I'll show it with a gsap codepen that i modify a little bit.

So when I first go the page, every thing works fine. When I leave the page the unload() function is called, locomotive.destroy() and triggers killing.
And when i come back, every thing seems to work until ScrollTrigger.refresh();
Can't figure it out, what i shall do
