I’d like to report on the current status of the investigation of this issue.
We’ve identified the code causing the bug and as an emergency fix we will be reverting back to the previous version of the code, but we are currently checking to make sure that doing this will not cause other bugs to arise.
The cause was a latent bug with the formula that determines the threshold value for switching between running and walking, and we edited the program so that issues would not arise when adding new features in the future; however, the issue at hand arose as a by-product.
Currently, we’re performing checks and as long as there are no new bugs we expect to release an emergency patch tomorrow. Once everything has been confirmed we will be making an official announcement about the timing of the patch.
I apologize for the inconvenience in the meantime.
