I second this always best to go and test out what works for you, and what doesn't. Personally wouldn't do minnow bots right now cause of how fast they're getting banned that's why the price of raw sharks going back up.
Provide logs then so he can fix the issue instead of saying its a persistent issue without providing logs to help solve it. My bots have been entering the bank pin just fine with this script. If you look at the image https://imgur.com/a/UGfZvfb the top right 2nd icon is to Copy logs then upload it to Pastebin and send to Token so he can fix it.
To confirm your saying the bank pin works just fine when using other scripts? Be better to provide the OSbot logs instead of blaming his script cause IDK how a script is supposed to enter your bank pin when it OSbot handles entering the pin.
It's OSBot not his script If its a Jagex account you have to use cli argument -bot username:password:1234 , Since you have bot manager you can also put the bank pin through the edit account of that bot.
Keep getting error "Error trying to login to Jagex account" for bot manager
Edit: was able to get that error to go away but having same issue of it getting stuck on "loading" say's "Failed to login to Jagex account Unexpected end of file from server"
