Loaded a Wendy Game I'd recently started with the WvtV update. All items with freshness ratings, such as food, parasol etc. Just had a brown background instead of their normal freshness colour/meter. This happened to existing items and items I picked up.
After playing for a while I quit out and came back in and the problem was fixed.
Abagail wasn't out yet. I haven't seen this issue before, so it may relate to the new WvtV update.
