Thanks for the feedback :) I hurried up and fixed the majority of the bugs you reported. They were very similar to some previous reports and were immensely helpful in tracking down the culprits. Next hotfix will be out soon!
For your suggestions:
I love the Geiger counter-like radiation indicator on screen. Right now, only a few places passively give radiation, like Swamps. I'll be adding more of these as time goes on.
Food can be found quite easily in barrels, but I do like that as a worldbuilding mechanic. Food merchants should be pretty easy to add.
For food about to spoil, do you mean a log message, or an indicator on the item's name? It definitely would be tedious checking to see which food items are about to go bad.
