Is it possible to refresh an index pattern and only add fields? We retire old logs somewhat aggressively, so if we refresh during a period where there are no logs with a given field, it will get removed from the pattern. This ends up breaking visualizations.
Unfortunately, I don't see a way to avoid this with your current workflow. There is a GitHub issue that covers this and some other pain points. You may wish to add your use case to that issue.
