So I was a little wrong before, the issue was actually the date. Now this is completely weird. Apparently one of the computers I’ve been working on does not have the right date set on it, so when flash tries to publish files from the future, it throws an error something like you have a naming conflict.
Recently I had this happen again, and apparently it was because my computer at home had its date set later, or my computer at work had its date set earlier. So when I brought the files home and worked on them / saved them, then brought them back to work I started getting these errors again. I finally found some developer in Asia working remotely with some company in on the East Coast having the same issue (because he was in the future). He said once he had the company on the East Coast change their date on their computer to the next day, all the errors went away.
So I tried the same thing, and boom my errors were gone. Just had to change the date in order to publish .as classes from the “future”. What an odd flash bug.
