Summary
In my map, the very first game session (first time pressing Start Game) fails to properly initialize device events. Timers show the countdown on screen, but their outputs/events often do not trigger, so Round logic doesn’t run.
After I manually press End Game and then Start Game again, everything works normally (even if it starts again from Round 1).
What I set up (important detail)
To test/force-skip Round 1, I set a 1-second Timer that should end the game / end the round using Round Settings Manager.
Expected
Round 1 should instantly end after 1 second (Timer → Round Settings Manager).
Actual on first session
Nothing triggers, even though the Timer numbers appears and counts down.
The Timer countdown is visible, but the “On Success/On Complete” style signal does not reliably fire.
As a result, Round 1 doesn’t end and other chained devices don’t run.
Random / inconsistent behavior (happened only ~2 times)
On two random occasions, during the first session:
The Item Granter gave some items to players (inconsistent).
Materials were granted fully (those worked).
But all other devices still didn’t function (Mutator/Barrier/Storm etc.).
This felt completely random and only happened twice.
Devices/logic affected (first session)
During the first “Start Game” session:
Barrier Devices are not disabled (Timer success event doesn’t trigger them)
Mutator Zone is not enabled by the 1s Timer
Item Granter usually doesn’t grant items on player entering zone (likely because Mutator Zone isn’t activating / triggers aren’t firing)
Advanced Storm Device doesn’t generate storm when it should be triggered
Works after restarting the session
If I do:
End Game
Start Game again
Then:
Game starts again (Round 1 again), but now the 1s Timer successfully ends Round 1 after 1 second (Timer → Round Settings Manager works)
All devices begin functioning normally after that
Key conclusion
This is likely NOT a “Round 1 bug”, but a bug with the first session initialization (the first time a match is started).
Devices appear active visually (timers display countdown), but their events/outputs aren’t firing until the game is restarted once.
Impact
Players can get stuck because logic doesn’t trigger on first session
Map becomes unreliable/unplayable on public/unlisted

Steps to Reproduce
Repro steps
Open map (UEFN/Creative edit session or published)
Press Start Game (first session)
Observe: timers count down visually, but device events don’t fire; round doesn’t end; chained devices don’t run
Press End Game
Press Start Game again
Observe: everything works (even starting again from Round 1)
Expected Result
During the first Start Game session, all devices should initialize and function normally:
Barrier Devices should be disabled when the Timer completes successfully
Mutator Zone should be enabled by the 1-second Timer ( timer device 2)
Item Granter should grant items when players enter the mutator zone
Advanced Storm Device should generate the storm form on succes by 5 sec timer- generate storm ( timer device )
Timer success events should reliably send signals to all connected devices( 1 sec timer for mutator zone, 5 sec timer for siable barrier device )
All behavior should work identically on the first session, without requiring End Game → Start Game.
Observed Result
During the first “Start Game” session:
Barrier Devices are not disabled (Timer success event doesn’t trigger them)
Mutator Zone is not enabled by the 1s
Timer Item Granter usually doesn’t grant items on player entering zone (likely because Mutator Zone isn’t activating / triggers aren’t firing)
Advanced Storm Device doesn’t generate storm when it should be triggered
