Internal error: Multiple tags with the same ID 'Bold' have different start tag properties

When received, it is IMPOSSIBLE to save the file and all work is consequently lost.

This atrocious bug has been addressed elsewhere, but I am opening up another thread because - unconscionably - this bug has NOT been addressed by SDL. Am I supposed to read through 14 pages of non-helpful responses to find, at the end, that the issue remains unresolved? Many of us have lost hours of time and inconvenienced our clients. This is unacceptable!
