Hi. Regarding this issue - it hasn't occurred in the last 24 hours but I'll provide details when it does.
Usual scenario: I'm building an Import from Salesforce action and I have made some fancy changes to the criteria but I don't like the outcome. I need to undo 4 steps So I hit control+Z ...
I would usually get the error on the first 'control+Z' hit.
The actual Undo icon was my workaround - I'll need to check that
