Hi @Willyham, I'm sorry you are experiencing this issue.
The 'Ran migrations' entry in history is expected, and although it shouldn't affect the state of your apps, we've had many reports on loss of progress that seem connected to them. Many users have successfully restored their application's state by reverting to a history entry just before the last 'Ran migrations' entry, which corresponds to the time the issue first arose.
We are still working on a permanent fix for this issue. You can see the whole thread here:
Please send me a DM with the id of your app, and an estimated time & date for when you lost your progress. I'm happy to help you recover the state of your app if you are unable to interact with the history tab.
From this error:
I suspect this is related to creating a new page/module that was not successfully saved, but some of its references did.
Did we remove any frames from the app?
On the other hand, could you expand on the following bug?
