Possibly incorrect min_fee calculation.

[Bromel777]

Hi, I'm trying to calculate min_fee for this tx by calling min_fee(true), the result is less than real.

Can you provide more info about the scripts used in those reference inputs? (size is the relevant thing here)

From where are they all being used? I'm guessing they aren't just used to spend utxos?

Could you share your tx-builder-related code?

@Bromel777 can you check to see if #359 fixes this?
