Crash completing quest in Faraway enclave

The quest was to rescue a villager . After winning the battle , the following crash happened :


############################################################################################
FATAL ERROR in
action number 1
of Destroy Event
for object obj_victoryscreen:

Unable to find any instance for object index ‘428’ name ‘obj_dutynpc’
at gml_Script_bc_HandleBattleAftermath
############################################################################################

stack frame is
gml_Script_bc_HandleBattleAftermath (line 0)
gml_Object_obj_victoryscreen_Destroy_0

One other thing , it seems like transmuting material doesnt give anything . Can you please check it out ? i tried to transmute 2 legendary material , and there were no screen with the result of the transmut , and it seems i didnt get anything from it .

Thanks in advance

Just had the same crash.
