[Therion] equate to non-existant station does not raise error

This may have been raised before. If a typing error is made in a station equate statement, no error is raised. For example in the following station kb51.29@kb does not exist, therefore the loop is not closed as the user intended. equate kb51.29@kb kb51.29@57 Can an error be raised in this circumstance please.
