Edited a large number of files and tried to perform a checkin. This froze initially so after a while I force-quit the app.
Now when i go back into my project, the "Pending Check-Ins" section just shows "Loading...". No idea how to proceed here.
EDIT: After leaving it for several minutes, a checkin eventually starts. But then stops with the following error:
"an item with the same key has already been added"
