Correct.
I restored the original file (and could'nt open the city anymore), opened the region and for each city but the one faulty:
- I opened it,
- waited for every message to be registered
- I saved it.
At the end I've tried to reopen the faulty city but... no way. The issue arised again.
I removed the 'delta' file and for each city but the faulty one I did the same procedure.
At the end reopened the faulty city but the progress of the region is still invisible.
I waited for one or two hours but... no way.
The progresses have gone...
I think that only the development staff knows how to reactivate the message broker to redispatch all the progress of each city...
I think that's the only way.
And I begin to think that the part of software involved in the original issue ("cannot open the city at the moment") could be the Message broker breaching the delta file (or whatever) actually.... supposing exists one to push all the messages in a region to the subscribed cities.
Any other idea?
