So when I loaded up 1.14.1 on my realm world, none of the repeating command blocks in a certain area of my realm world worked. I had to reactivate them before they worked. Always active command blocks had to be set to needs input then back to always active before they worked, and repeating command blocks powered by redstone blocks had to have the redstone block destroyed and then replaced. It's extremely inconvenient as now we have to edit all the repeating command blocks. Edit: After reloading the world it turns out everything became un-powered again so its simply impossible to continue working on the map now unless we use older versions. I also tried downloading the world to my single player worlds and it still doesn't work.
