Occasional game crash when doing damage

  1. Crash

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

DoDiv :1: Execution Engine - Cannot operate on string type
at gml_Script_bc_EventDamage
############################################################################################

stack frame is

  1. I have high performance mode and frame skipping enabled. The crash seems to happen when mashing through battles by casting the same spell. It takes anywhere from 3-20 battles for the game to crash. I estimate that I am pressing the E button about 10 times per second.
  2. Windows
