The enum variable always saves next unused constant number

Lets start in our enum

pawn Код:

enum CTask //normal mode (+= 1)
{
    int:iSleep, // = 0
    int:iRemainingTime, // = 1
    int:iType, // = 2
    sParam1[256], // = 3 - 258
    sParam2[256], // = 259 - 514
    bool:bActive = false, //normally 515 but we set it to 0 again
}; // => last constant number + 1 step => CTask = 1

new pTasks[MAX_TASKS][CTask];

Now it should be clear why the out of bounds error appeared

Since all variables are by default 0 (false) you dont need to set bActive to false
