delete random, unused column from production database
entire app blows up
re-release last change on code pipeline
everything works beautifully
¯\_(ツ)_/¯

that's probably it, but I did it on my dev environment first without a hitch. the prod server must be treating cache differently.

Happens all the time with Entity Framework as it selects by column name every column in the table (unless specifically told not to).

We tend to push the latest code first, wait a week, then run a cleanup script to drop the orphaned column.
