I have no clue who downvoted this, if you have advice on how to fix this problem, fell free to add a note. There is no reason to vote this down. If this is a problem that is often reported by amateurs, so be it, just say it. Maybe provide a link to a solution? Don't be a jerk.

Triggers are created on every machine, that is to say their code will be executed on every machine when activated.

It sounds like you're running into a simple locality issue.

I have no idea what the spawnGroup command is (as far as I know there is no such thing), but you basically need to enclose your code in:

if isServer then {
<your code here>
};

I downvoted because this isn't really something that belongs on the tracker, the forums are a better place for solving mission making issues. Sorry I didn't have time to write a reply at the time.

Edit: Another solution is to edit the condition field of the trigger to say "this and isServer" - probably the simplest solution really

Hey thanks for answering!

I thought it was some kind of locality problem, but then i dont get why other triggers, that spawn text using sideChat, dont trigger twice? That is what had concerned me the most. Do you maybe have an explanation for that too?

The spawnGroup command is basically the script equvivalent to the editor F2 function (add preconfigured groups). But you can tweak certain variables, like skill range, rank of units, etc. by giving them to the function. Quite usefull if you want to spawn those groups after initializing the mission.

Thank you for giving that important info that appearently can't be found elsewhere..i've been searching for 2 hours on various forums...

I'm going to try it right away and report back in a few minutes.

Side chat only works on client so you dont see the server execution. As it has been pointed, it is not a bug, you should getter a better response on the forums.

I just read that. I seem to have overlooked that part...thanks Killzone_Kid for pointing that out!

I guess this can be closed now.
