Yup -- fairly much every network engineer who has deployed HSRP  /
VRRP / <insert favorite vendor acronym for same> has the story of both

and the "redundant" switch link becoming active, etc etc etc.

Often adding redundancy causes more issues than it solves...

idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.
