That's quite odd considering you are defining self.targets in init. Nothing in THAT script (as far as I see) should make self.targets = nil, so I'm thinking maybe to do with a state machine etc? I'd think something somewhere is re-defining self. Try swapping all instances of self.targets for storage.targets etc to move it off the self table.
