We are having trouble creating new issues directly from plans. We'll create a draft issue on the plan, schedule it and add detail (such as start dates, due dates, dependencies, child issues).

We then open up "Unsaved Changes" and save the new issue. We then get an error message that says "Couldn't save changes", with a prompt that asks us to "Open Unsaved Changes".

When we open up this prompt we get taken to the "Create Issue" screen where it says that that required fields must be added. However all required fields are filled in from Plans, and we can simply hit "Create" from this screen without making any modifications to the data.

We've checked that the users who are creating issues have the correct permissions, and we've also checked to see if there are any validators on the workflow for creating an issue and confirmed that there are no hidden validators.
