What major mistake did the new American government make with the Treaty of Paris 1783

I think it's that the Congress had promised at the treaty of Paris that all debts should be paid, and that all the Tories, or friends of the king, in America should be protected. But the British soon complained that they couldnt collect their money and it was plain that the Tories were badly treated, for in two years more than hundred thousand left the country to settle in Canada, Florida or Bermuda. (I got it from the internet btw)
