Same, everyone else is done but Maria just shows there is an event available but it will not trigger
The bug was in version 0.17, It was fixed in 0.18.
This is the second time it is claimed it is not fixed in 0.18. It did not happen every time in 0.17 either, I did not see it. Maybe it is not completely fixed and can in rare cases still appear in 0.18.
