Ubisoft has released a list of already known problems in the official The Division forums that can occur while you are playing the closed beta in the next couple of days. The developers are aware of them, so be sure to read the list before you submit a new bug.

There is nothing to worry about though and you will maybe or most likely stumble upon the one or other new bug that’s not listed there. If so, please don’t ignore it and go to the official closed beta forums to report it as detailed as you can!

More information about the beta and its start times or on the subreddit /r/thedivision.
