translation missing: en, field_watcher_users is invalid
I came across the following error whenever someone would create an issue with me as a watcher:
- translation missing: en, field_watcher_users is invalid
It did not do the same for anyone else. And, I could be added as a watcher to an issue later.
I figured out the problem, and hopefully this will be a helpful hint if someone comes across this rare error. It turns out that my email address was in use by both my account and the "Administrator". So, I changed one of the email addresses and it started working correctly.
The current release does not allow this to even happen, but I assume I set this up in a prior release, or by manually editing the database. In either case, most people shouldn't come across the issue and I don't know if this is something worth looking into fixing.
