problem - wywalanie podczas otrucia, utrata uprawnien

[axe321]

Cześć.
Gdy gracz na moim serwerze zostanie otruty to go kicka, i traci uprawnienia. Nie zawsze tak się dzieje ale jednak często się zdarza. 
Nie wiem od czego to się dzieje. 

Konsola wywala takie coś:

masz jakiś plugin modyfikujący efekty czy coś? wygląda to na błąd związany z iterowaniem, polegający na tym, że dokonuje się próba zmodyfikowania wpisu przy iterowaniu listy, a dany wpis nie jest dostępny, więc najprawdopodobniej jakiś plugin to robi.

 

podaj liste pluginów.
