Calling this crashes the game 100% repro:

Func(Agent:agent):void={
    if(X := set GlobalInt[GetSession()] = if (Y := GlobalInt[GetSession()]) then Y + 1 else 0){Print("{X}")}
}

All details here:

Hey Finest. :slight_smile:

@JoeriDukker - could you send me over the code you’re using with plain map that doesn’t fail?

}
FuncFromEpicPost(Agent:agent):void={
    X := if (Y := GlobalInt[GetSession()]) then Y + 1 else 0
    if:
        set GlobalInt[GetSession()] = X
    Print("{X}")
}
Func3(Agent:agent):void={
    var RegularMap:[int]int = map{}
    if(X := set RegularMap[0] = if (Y := RegularMap[0]) then Y + 1 else 0){Print("{X}")}
}

Func3 uses regular map

Thank you!

Confirmed broken for round based games. GetSession and weak_map work fine in game modes that don’t have rounds.

Same here, also having session crashes when using weak map.
