My custom Scenario gets Saving Sync Error or Out of Sync (OOS) error at a specific spot in the scenario with 2 or more players. I'd like to consider myself an experienced multiplayer scenario designer and I believe I avoided all triggers to cause this but I'm still getting the error. Any information would be appreciated.

Error details:
I have a Counter add Timer which countdowns until the cinematic starts. Once the cinematic starts we get the OOS error.
The counter is not linked directly to a trigger. I fire a separate trigger which a timer which starts the cinematic.

Starting the Cinematic:
These are the effects which trigger when OOS happens:
Change unit type: cinematic block
Camera track (again, not linked directly to a trigger)
Cinematic mode: on
Destroy: Cinematic block
Fire event (a timer trigger with the next step of the cinematic)
Play dialogue (only with subtitle and portrait, again no direct trigger connected)

I've scoured the internet and tried everything I've found spending about a dozen hours trying to resolve this. If anyone has any insight I'm all ears. Thanks
