The distribution of Divisions between teams in the current session of Brawls (12 vs. 12 aboard battleships) is not working correctly. Therefore, we’ve decided to temporarily disable the ability to join Brawls as part of a Division. This will apply to all remaining Brawl sessions in Update 0.11.8.
We will notify you as soon as the issue has been solved. We thank you for your feedback and extend our apologies for any inconvenience caused.
