From a comment on the Kickstarter page, it looks like someone was trolling by donating almost enough at the last second: My wife continued watching, as I went off to bed, and I heard a loud gasp... (her hands were up on her face as I walked back in). The final bump that put it up to $49972 appeared to come from one backer's pledge raise in the final seconds, when nobody could do anything at all (like single digits of seconds). That person raised by over $800 at once, but chose (WHY?!) not to go in another $28. My perspective is that it was on purpose, they did not have the funds available, and they wanted to make a point. Otherwise that pledge (and a corresponding comment!) could have come with a minute to go, and a chance for me (or others watching) to kick in the final dollars.
