I assume that this happened after a photon car got spawned via a car dealer (spawned correctly).
It seems that a car with components, which use bone manipulation, caused this error. The props of the car didn't get spawned. Error got spammed while the car was still on the world.

[creator2013]

According to someone in photon support he gets this error as soon as a photon car leaves the players rendering radius. The props will stay in the position where the car left the radius.

[CGMonkey01]

I am the person from photon support. Information was miscommunicated. The components and props stay in the position where the car left the view radius, but I only get spammed the error when the car activates its lights after it reenters the view radius. The floating components do not activate, they are just the models. However, this is all inconsistent and hasn't proven to be a reliable way to recreate this error.

My vehicles are spawned through the spawn menu. No car dealer.

Result of adding code to line 141:

print(name)
print(option)
print(vehicle)
if IsValid(vehicle) and name then print(EMVU.Sequences[name]) else print ("1") end
if IsValid(vehicle) and name then print(EMVU.Sequences[name]["Traffic"]) else print ("2") end
if IsValid(vehicle) and name and option then print(EMVU.Sequences[name]["Traffic"][option]) else print ("3") end

So from doing some random testing. Does not work being near each other. At a far distance, if you spawn your car right after the other person spawns their car you have a chance of getting the error when they turn on their lights. I was able to reproduce it a number of times but not consistently every time, which may have come down to timing trying to spawn my car after he spawns his car. Sometimes, if you did it quick enough and already had errors, they could spawn their car and you would see no equipment on the vehicle at all, nothing spammed in console, and no errors.

Hope this helps. If you need anything else, I am glad to help some more.

[creator2013]

After following the code, the only reason why option is 0 would be because GetNW2Int returned the fallback because it wasn't able to get the var.

[CGMonkey01]

The car does have auxiliary lights. Also, error occurred today when i joined the server and he spawned a vehicle right next to me.

Line added:

if IsValid(vehicle) and name then PrintTable(EMVU.Sequences[name]["Traffic"]) else print ("4") end

After some testing on the server of my friend I get this result:

It is indeed a networking issue and the default value causes this error to occur

[creator2013]

#166 probably fixed this. Closing.
