You Identify an Element in Application Modeller and It Highlights

You identify an element in Application Modeller and it highlights uniquely and can be used in your object flow diagram. The next day you find that Blue Prism cannot no longer identify the same element, your object flow is giving you 'Element not found' exceptions. Which of the following statements is true?

A) This must be an environment issue. The Blue Prism environment must be consistent and persistent, and an element that worked one day and does not work the next day suggests the environment is changeable. The IT team supporting the environment needs to be contacted to fix the problem.
B) The Blue Prism product support team should be contacted to report the issue. This signifies an inconsistency in how the Blue Prism product is working which needs to be fixed.
C) This suggests that Best Practice exception handling has not been implemented in the object. A retry loop around the object stages that are using the element will probably fix the problem.
D) It is common for consistency issues to be found during configuration/development testing. The most likely cause is that an attribute has been selected for the element that is changeable, such as a window title with a date, or a URL. The developer needs to ensure that any changeable attributes are unticked.
