Well, I don't think this will solve your problem but I think your parameters is wrong of SetSpawnInfo(playerid, 0, 299, Player[playerid][Position][0], Player[playerid][Position][1], Player[playerid][Position][2], 1, 2, 3, 0, 0, 0, 0, 0, 0, 0);. According to https://sampwiki.blast.hk/wiki/SetSpawnInfo there's only 13 parameters.
