pawn Код:

new rand = random(sizeof(RandomPlayerSpawns));
...
SetPlayerPos(playerid, RandomPlayerSpawnsbf[rand][0], RandomPlayerSpawnsbf[rand][1], RandomPlayerSpawnsbf[rand][2]);

pawn Код:

new rand = random(sizeof(RandomPlayerSpawns));
...
SetPlayerPos(playerid, RandomPlayerSpawnsarea69[rand][0], RandomPlayerSpawnsarea69[rand][1], RandomPlayerSpawnsarea69[rand][2]);

and so on..

That's incorrect. You need to get the size of each array separate and not from RandomPlayerSpawns.

do the same for the rest.
