I just had someone h/p for me. She ran out of fuel, and the game wouldn't let her use my fuel!
I know that you've told me that this issue has been fixed, but it obviously doesn't work all of the time.
She said that she'd been having problems like that at other farms also.
I'm not sure where to post this question, so I'm afraid that I'm going to post it here for now. Sorry if it isn't the right place for it!
