No clue what's going on here, this is a strange error that's making me halt the progress of my game ! =(
So far I have 9 enemies created. 8 of the enemies work fine, but when I go to the certain map with the 9th enemy on it, the game instantly crashes with this error:
Script 'Game_Battler 3' line15: NoMethodError occured.
undefined method `sp_cost' for nil:NilClass
Could I get some serious help on this, it's really slowing me down.
