It was brought to our attention that a few alliances were experiencing issues with levelling up and crashes earlier today. We have now released a hotfix so although the alliances affected will keep raising levels, we hope you will no longer be stuck in a crash loop. Please do alert email@example.com if that is not the case.
In the meantime, we're still advising players to do the event elsewhere just be on the safe side while we continue investigating the issue an working on restoring the alliances' old levels, though this might take a few days.
If you're leaving the alliance to do the event elsewhere, please make sure to leave at least one account in it so it's not lost (we cannot give back empty alliances).
We sincerely apologize to everyone affected by this issue for the inconvenience this may have caused.
