I am getting this error message when trying to publish my customization (also firsts comes up with SQL server error), all I did was add a new option under an option set field, I tried removing it again and then publishing but nothing. Error code in SQL error is 2147204784
The server has 30GB free so it's not that, I have also tried restarting it.
I have now also tried importing new data and it fails. Same error code as above.
