### Problem with Editing a Committed Match in FTC Live Scoring Software v1.1.1 (*Listed 10/22/19*)
### Problem with Editing a Committed Match in FTC Live Scoring Software v1.1.1 (*Edited 10/25/19*)
There is a [known bug](https://github.com/FIRST-Tech-Challenge/scorekeeper/issues/430) in the FTC Live v1.1.1 software that causes problems if you try to edit a match that has already been committed in the system. If you do this, the edit match page might display all zero/blank values even though the committed match should have non-zero values. Thankfully, when this happens, the match data is still stored in the database and the results have not been lost. Only the screen displays empty values for the edited match.
If you find that you are using the v1.1.1 software and you need to edit a match that has already been committed, then please watch the following YouTube video and use the workaround procedure as described in the video.
If you find that you are using the v1.1.1 software and you need to edit a match that has already been committed, then the easiest course of action is to press the F5 key on your laptop to force Google Chrome to refresh the page. Refreshing the page should populate the page with the previously committed match data.
You can also use the procedure in the following YouTube video and use the workaround procedure as described in the video, if pressing F5 does not work for you.

Thank you Richard Lester from the great state of Indiana for figuring the F5 (refresh screen) workaround!
### Problem with the Direction of some GoBilda motors (*Listed 10/3/19*).
Mr. Phil reported on the FTC Technology forum an issue that his team detected with some of their recently ordered GoBilda motors. They found that when they applied a "positive" power to a new motor, the encoder counts went in the opposite direction. They examined the motors more closely and discovered that + and - power cables/leads were connected in the reverse direction from what they normally are.
