Script Anihi pequeno erro

(Creio que está na área correta) Galera, estou usando esse script para uma annihilation e está funcionando perfeitamente (uso tfs 04, 8.6). Porém quando os players são teleportados para a quest, os bixos são sumonados normalmente mas ao invés dos bixos sumirem após o time terminar a quest, eles continuam lá. Assim da erro na distro quando o próximo time tenta realizar  a quest, porque não consegue sumonar os bixos uma vez que os bixos da quest anterior já estão vivos lá. Suspeito que seja essa parte do starting/ending, e se for mesmo ela, qual posição eu pego para por nisso ? Se não for também preciso de ajuda. Só falta isso para o script ficar bom !
