I posted this as a bug, instead of just a Technical support issue, it was moved to Accepted, and then to Not a Bug

Hopefully, if more people see this issue and report it, someone on the dev team will be able to reproduce it and fix it, or roll back the change in 2.28 that caused this to start happening
