I did set a gas limit, but I have no idea what the translation is. Min Gwei is 10, Max is 500. It kept telling me it wouldn't pay out til it was under my limit, so I kept increating my limit. I didn't realize 250 Gwei = 0.0045 ETH (even through that's not actually the case)
I don't think this is exposing keys or anything, but this is my Jul 27 transaction vs my Aug 27:
