Crash occurs when interacting with cookie. My food history is, I think, empty due to recent death but I am in the diminishing returns phase.

S:food.modifier.formula=IF(count=0,1,((0.5+((((0.5+MAX(1-(count/cur_history_length),0.1)/2))*(((distinct_food_groups_eaten/(total_food_groups-1))+2)/3))/2))+(food_group_count/(total_food_groups-3)))/2.2)

"An ArithmeticException is only thrown with the message "Division undefined" when you attempt to divide zero by zero."

You have to make sure to protect against things like this is in your formula. Likely due to this part, assuming count is 0 and cur_history_length is 0:

count/cur_history_length

Aha, I was catching for the numerator being zero, but not the denominator.
