Can UUID change?

In some unknown circumstances, it seems that UUIDs are changed in Conditional Controllers. I use conditional because I am not completely sure and I could not identify the event.

UUID should never change.

Are they defined once for ever in the code? If not, in which circumstances can they change?

No, they don’t change.

That’s a good piece of news.

What’s leading you to believe they’re changing?

As said, I was not sure. It seems I have made more mistakes than expected. I had to check with you about the design. This is related to feature request #1204.
