Every site has its own field as now you can launch different tasks to your sites. You can find it under the "Remote Tasks" row:
Where do I check the latest task launched?
I haven't experienced this behavior. I will be alert.
I have also been experiencing some weird issues with the integrity check, where it tells me from the dashboard that there are new/modified files, but when I go to the integrity check page and it shows me x number of files modified, there is nothing in the list below, and if I start a new scan, it tells me there are 0 modified files, even when initially it showed me that there were 68 modified files... I will try and get a screen grab if it happens again.
