I think we have until the end of this month so I wouldn't worry....YET. In fact, I don't know what exactly happens if we have a shortfall where we don't get enough money.
I understand why it's been taking longer to meet the goals and it has to do with the cost of, well everything, going up in price. Less disposable income available. For me to keep donating the same amount, I had to cut back on other things. I love this game and if I have to give up on drinking coffee or dropping Netflix Canada I will do that too.
