ForAttrRegionFreeAngle: SECTREE_MANAGER::ForAttrRegion - Unhandled exception. MapIndex: 41
ForAttrRegionFreeAngle: SECTREE_MANAGER::ForAttrRegion - Unhandled exception. MapIndex: 21

For this error I have searched in google that corrupt or mismatched "server_attr" can cause this problem.
So I replaced this file "server_attr" from Metin2SG game34083 but again & again I am getting same error on my syserr.
Even I tried generating new server_attr using Metin2 Map Tool v1.4

My game file version is also 34083.

What should I do to solve this probelm?
