May u know. - Instances crash when you kill mobs

Hello, I'm getting a problem with hrace009 server files.
It run good but when u enter to any instance in squad, when u kill any mob, map cash.
I'm using task.data from ronny1982 and aipolicy.data too.
1.4.2 downgraded to 1.3.6
Any can help me or tell me where i can take a look?

Thx ;)

There could be some reasons for crash..

1) Your mobs in elements.data(page 38) contain drop items, which doesn't exist in el.data.
2) Sum of all drop rates(38 page) must be = 1
3) This mobs may use aipolicy strings that not exist.

p.s. sorry for bad english

Ty for reply :)
I dont have drops changed, I'm using default drops.
May is how you say, aipolicy.data, cuz i have it remplazed for another one by ronny.
And ur english is great, much better than my english.
Imma check it in a few, I'm at office atm QQ
