I have been testing WSFW food and water for a couple of games. Testing maybe not the right word, observing would be better. Not that I really care as it is mainly unimportant to my games, but there were so many complaints posted, I thought it was worth a look. Most of the time I get some water but not nearly relative to the purifiers. I might get X at one location and add two more purifiers but still only get X. Remove the original purifier and replace with a smaller one, still get X. Food is the big issue, almost always get zero yet some locations do add to the totals. I have not been able to connect why. Both are really messed up and need repair.
The mess was created when the option to allow or disallow settlers to consume everything in the bench or only basics was added. I have an Xbox at the cottage that is not connected to the net and runs a version of WSFW prior to that change and the returned water and food seem to be balanced and near perfect, but still don't reflect the numbers I produce, so capped. I also noticed this as soon as that update went live. I reported it then, but my observation was about all the good stuff was consumed first before crops, but had no idea I was not getting any crops added, that would explain why all the nuka, meat, and prewar was being consumed first, there was nothing else.
I have some screen shots around as I planned to do a post, I will dig them out and put them together. I did things in game to make sure things were accurate, like not making anything at a bench, made sure I had no mods affecting number etc. I have also tried several mods that might "fix" this and the results were never nice. Either way too much or could not bust through the WSFW block. It would be nice if it was fixed as it has been made clear that WSFW does try and fix the original coding by Bethesda which was wrong and to favorable. The current fix is not a fix, makes things worse.
