So Brownie in Ultima 7 offers to pay me 1 gold for every pumpkin I bring him. Simple enough, except I can't pick up the stupid things. I've found two fields full of immovable pumpkins. I know that the baker offers to buy flour from you for less than you paid for it, so is the pumpkin deal a dummied out feature, or just some sort of joke?

You can't pick the ones from the fields, but you can bring him any others you can find. There's a pile of them near his fields, for example.

Oh bloody hell. Thank you. I was just about to go on a rampage with powder kegs.
