You know this just drives me nuts:
"A bunch of votes were just found."
A bunch of votes have never been counted. Mail-in ballots continue to flow in after election day, and are valid. Provisional ballots require hand counting and are never available on election night.
538Given the extremely long wait times in these Democratic counties, a lot of people have wised up and use the mail-in option. Republican counties have an easier time voting in person and so they are usually more completely counted on election day.
The "found ballot" meme makes it sound like there are hundreds of illegal aliens furiously filling out extra ballots and then shady Clinton operatives are slipping them into the pile.
There are some exceptions, there were 266 ballots found in a mail facility for instance. But this isn't why we are seeing the bulk of additional votes being tallied.
It is also interesting to note that when the news or the state government declares "precincts reporting" it may not mean what people think. Many states have county vote centers which are not in the precinct totals. Mail-in is not in the precinct total in some states. Precincts are also not proportional. I don't know how much that applies to Florida, but it is counter-intuitive and something I didn't understand until the past few years.
