UT Editor- Is there a round start event or something similair

Hello everyone
Im currently working on a university project in which we are creating a level for the new version of Unreal Tournament, I have created a small interactive map feature in the levels event graph that creates fire and damage after a set delay but when tested I came across an issue where diffrent players have the fire come at diffrent times due to thier diffrence in the time joined as the script is currently started by the begin play event. The map is using a CTF style game mode so i was wondering if this came with any events that fired when a new round is started which could be used to remove the diffrence betweens players time visibility of the flames.
I am ok at using the editor but am not completly versed so if something is super complex you might need to explain in detail. Any help would be appreciated.
Kyle.

Thanks for the quick reply i will have a look and see if this helps.

I don’t know UT APIs but UE4 got OnSetMatchState which triggers when match switch between varius states like warm up, match end of match etc. UT probably use it

Problem is it protected event and you would need to override GameMode class to implment it practicly creating new mode. Bte why player runs got fire on diffrent time if you put you code in level blueprint?
