Scratch that, definitely found the issue. The extractors should have been running between 0-1 to give a nice .25 or .5 to multiply the resulting production by. What was happening was some had 0-100 as the range, especially in the milkmaids checks, and a couple even have rounding on to give up to 100 times the produced amount. I corrected it in v1.3 and will try pushing that out as soon as I ensure no more bugs related to that, to get that fix out.
As a patch for the milk merchants for now, there’s a final check that will ensure they never sell for less than the cost of a bottle. Just a temp patch to make sure you don’t lose money in case the milk merchant bombs out a towns interest until the rework concludes.
Also fixed the issue of the farm not running at all if no cattle were found. Sneaky little “return text” snuck in there near the top. Corrected. Thanks for the detailed reports mate, they helped me track it down immediately.
