Just finished a split brew session. can't remember if I selected to deduct all inredients from inventory when i first started the brew session. today i finished up the boil this morning but i had two brewers friend windows open. i went into one of them and selected -edit brew session- and selected deduct ingredients. looking at my current inventory, remaining amounts of the items i used appear to be off. For example (opened a 4oz pack of simcoe, used one ounce in the recipe, inventory shows 2oz left) Is is possible this could happen? can it be undone or will i have to change figures in the inventory?
