[Script error on autobonus line 0]

I did not modify the script and as far as i can see there is no missing { in this.

The script is found in the item_combo_db.txt and looks like:

1287:15123,{ if (getequiprefinerycnt(EQI_HAND_R) >= 7) { autobonus "{ bonus bIgnoreDefClass,Class_Normal; }",1000,3000,BF_SHORT,BF_NORMAL; }  /* Confirm: Success rate */ }

Maybe i'm looking in the wrong place?

 

[Script error on autobonus line 0]

Heya, i'm new to rathena and can usually solve my issues just fine with a quick search but this time however,  i have no clue.

There is an error every time the Whikebain Suit [1] (Item ID:15123) is equipped.

How to i proceed to solve this error?

Edit: The error is only there if the Whikebain Suit is used with the Durga [1] katar (Item ID:1287).
