Stuff that works "offline" dont work when players join

[kocrachon 2]

I normally create all of my missions by hosting an online server and using the mission editor there so I can adjust things on the fly. However, unlike in ArmA 2, where if it worked there it worked online, things are not working.

One specific issue I am running into is I have a car that has dostop car1. When I run it with just me in the server, it works fine, but the minute I have other players in, it doesn't work anymore. Anyone have any idea why? I never had this issue in ArmA 2.
