Crash after defending with a dreadful efreet in the arena

Windows 10, Siralim v0.5.5. One enemy had burn at the time.


############################################################################################
FATAL ERROR in
action number 1
of Step Event0
for object obj_battlecontroller:

trying to index a variable which is not an array
at gml_Script_bc_OnDefend
############################################################################################

stack frame is
gml_Script_bc_OnDefend (line -1)
gml_Script_bc_CreatureDefend
gml_Script_bc_Turn
gml_Object_obj_battlecontroller_Step_0

This happened to me again, outside of the arena, against a mimic with burn. Version 0.6.0

Found it, thanks!
