What went wrong?

Well, I use APE on testnet to generate a bunch of data for my web interface. With old version (I’m not sure what exactly version I have, maybe 1.5 or maybe 1.6) I ran with command ape run deploy_testing --network ethereum:rinkeby:infura I signed the first tx:

Sign:  [y/N]: y
Enter passphrase to unlock 'trader03' []: 
Leave 'trader03' unlocked? [y/N]: y

After that I just leave unlocked account and wait when script will done.

Well, I decided to rewrite some test from Brownie to APE and check how it will going. I installed ape-hardhat through PyCharm Python Interpreter. As I understood APE updated too automatically.

If the script has:

    owner = accounts.load("trader03")
    owner.set_autosign(True)

I hasn’t any problems. But if delete these strings and continue to Sign Tx with hands when the next message appear:

Sign: [y/N]: 

it will react only positive, so if I type y,Y,n,N, or tap on ENTER, the result will be always Yes.

How to reproduce:

token: https://github.com/vyperlang/vyper/blob/master/examples/tokens/ERC20.vy

deploy_testing.py:

from ape import project
from ape import accounts

class InitToken(object):

    def load_accs(self, type):
        acc = accounts.load("trader03")

        if type > 0:
          acc.set_autosign(True)

        return acc1

    def create_token(self, name, symbol, decimals, supply,  owner):
        token = owner.deploy(project.Token, name, symbol, decimals, supply)
        return token

    def token_approve(self, token, receiver, amount, sender):
        return token.approve(receiver, int(amount), sender=sender)

random_addr = 0xDf032Bc4B9dC2782Bb09352007D4C57B75160B15
### works fine with set_autosign
deploy = InitToken()

main_account = deploy.load_accs(1)
main_token = start_deploy.create_token("NAME", "SMBL", main_account)
deploy.token_approve(main_token, random_addr, 1e18, main_account)


### check Sing Tx without set_autosign and type N
deploy = InitToken()
main_account = deploy.load_accs(0)
main_token = start_deploy.create_token("NAME", "SMBL", main_account)
deploy.token_approve(main_token, random_addr, 1e18, main_account)
deploy.token_approve(main_token, random_addr, 1e18, main_account)
deploy.token_approve(main_token, random_addr, 1e18, main_account)

NOTE: First tx I signed and leave account open.

Sign:  [y/N]: y
Enter passphrase to unlock 'trader03' []: 
Leave 'trader03' unlocked? [y/N]: y

if account is locked, then everything works fine.
