Help! Unity PreLateUpdate.ParticleSystemBeginUpdateAll

I'm in trouble I can't find the source of my issue. Here's a screenshot of my profiler. because of this weird call, my whole program is slow while it should be lightning fast. Anyone got an idea to get me out of this mess ?

I deactivated all particle systems and still had the same result with no particle system in my game.(and those i have are minor 50ish particles torch effects)

Can anybody help me out ?
At this point, any idea even the weirdest ones are welcome :p
