Not sure if it’s a bug or just plane coincidence, but since the last update 9/10 traders that stop by request to trade their items for farmers hoe’s. I can’t really tell how to recreate the problem since I’m not exactly sure it’s a bug.
It just stood out for me as weird
haha maybe the game is telling you your hearthlings are starving 
At least they’re asking for something easy to make. At least it levels up your Carpenter faster. I’ve noticed it too, but it depends on what they’re trading if I accept or not.
I’ve had many come in requesting Wooden Doors. 8 12 17 etc and getting bronze BPs, Gold bars etc. I dont mind 
you are so lucky 
I’ve gotten some pretty hilarious trade offers. One time I got them asking for like 19 fences in exchange for two doors…
That’s nothing. I got 42 fence doors for some baskets of corn and afterwards the traders wanted only fence gates Got me some really cheap iron mails.
Yeah, we had this old thread about the offers

Just got 1 picket fence for 1 bronze BP, 48 hours. SURE no problem
