We identified and fixed a technical glitch after enabling the recruiting event that would cause the Tentlan to crash in certain cases after recruiting units. The issue was first spotted at around 01:00 CEST and we immediately began working on a fix. After due testing the correction was pushed online to all servers in all countries at approximately 01:30 CEST (about 10 minutes ago from the time of this post). Everything should be back to normal now and this issue should have caused no losses on resources or units.
We are very sorry for the inconvenience and will put measures in place to prevent this sort of error from happening in the future again. The recruiting event will continue as normal and you'll be able to recruit faster for the duration of the weekend as originally promised.
Your Tentlan Team
