I'm not sure if there is an issue with the system this morning but halfway through playing my last two games it popped up saying I had resigned but I didn't press the resign button
It happens to a small number of people that are somehow in 2 games at once.
If it happens to you, the best bet is to stop playing until two hour-changes (e.g. 8:59 --> 9:00) have happened. Then any games you may have been in without actually playing are gone.
Thanks for letting me know. Is the bug being looking into?
The same happened to twice right now.
