"There was an error while saving your form. Please contact our support team."
How to replicate this error:
1. Create a form with a lot of fields (~40).
2. Duplicate that form.
3. Edit the duplicated form by deleting ~35 of the ~40 fields.
4. Try to press update.
I am also noticing a number of other bugs, for example if you want to add to fields (of the same type) and you press the button twice quickly, it can something input the fields with the exact same ID number.
