The guest record on an Event only updates if changing it directly through the event. It does not update if changing the address from the guest information found through the corresponding constituent record whom they are a guest of.
We have evaluated this issue as a bug and we have determined it will not be addressed in the program in its current state. In this case, we believe the risks and challenges outweigh the potential benefit of resolving this issue. We strive to select the most impactful changes and issues to address with each release to accelerate the rate at which we deliver new features while sustaining the highest level of quality for our customers. We would certainly recommend adding this program suggestion to our Ideas Community page. Our developers check here first when building program enhancements to see what our users are most interested in seeing implemented.
