I have a workflow that is started by a Forms process and the Workflow then retrieves variables from the Forms process to use later on. Forms is on version 11 and the Workflow server is on version 11 as well. The Workflow Designer is version 10.4.3.139 because we can't install the Workflow Designer on the end-user machine currently without installing IIS.

If we open this specific workflow, don't make any changes and then Validate the workflow, it removes a Forms variables that we configured to retrieve. If we fix that variable by reselecting it, validate it again, then it gives additional errors about variables that are used in the Set Business Process Variables activity as well. I have only tested with this one process so far, but wanted to see if anyone was aware if this is a bug.
